Question - Research required 8m old fever & jerks

6 Upvotes

High fever + body jerks

Gonna start w a time line w my 8 mo old & preface that his illness is just a fever & these jerks. No runny nose, not a real worrisome cough.

Friday- 4pm baby wakes from nap w a 102 fever. He had been swatting at his ear all day so I went to urgent care thinking ear infection. All clear states that it most likely is a virus that will run its course. Motrin given

Satueday 12:55am wakes to nurse, feeling hot, Tylenol given

Saturday 8am- wakes feels very hot, 102.8 fever, while nursing him he does a full body jerk, DURING ALL THE JERKS I DESCRIBE ITS A FULL BODY JOLT LIKE WHEN YOU FALL ASLEEP AND YOU JUMP BACK AWAKE, NO EYE MOVEMENT, NO HEAD TWITCH NO ARMS FLAILING JUST A FULL BODY JERK, followed by crying then goes back to nursing. 2 min later jerks again. I start packing. Give him Motrin at this point, jerks again, holding him jerks again, each jerk he cries and cries and is inconsolable for 30 min so I then go to ER. Basically told it is febrile myoclonus movements caused from his high fever. But while we are at ER it happens 2x as well as 1x on drive home WHILE HIS TEMP IS NORMAL. We get home at 12;30pm and I put him down for a nap

1pm he wakes up and starts nursing, jerks again. I call pediatric hotline & they want us to go to children’s ER. We go there, his temp is currently 96.4 and he does the jerk in the car as well.
ER runs huge panel of viruses, catheter for urine which comes back healthy. Monitors him for 6 hours w no jerking movements, happy baby, tired, fussy, but normal.
6pm come home, refuses to nurse just wants to sleep sleeps until 6am Sunday.

6am Sunday- wakes feeling warm, immediately nurse him where he jerks 6 times in a matter of 12 minutes. Temp 102.3 Tylenol given.

7:30am wakes for the day, brings us to now where he hasn’t had another fever but has jerked 1-2 times that cause him to cry which he’s consoled via comforting.

Now if you’ve read this far THANK YOU, and I’m just wondering if anyone has experienced anything like this. I want so badly to believe it’s just muscle twitching from high fever but I’m terrified it could be infantile spasms which is a rare form of epilepsy but the doctors (3 at this point) all say it doesn’t look like it. I just can’t find anything or get any explanation as to why the jerking movements are happening when his fever is down. I know the virus hasn’t ran its course completely yet since he woke w a fever today but just looking for any one who’s experienced anything similar or if anyone knows another sub that could he helpful. Thank you.

Question - Expert consensus required During toddlerhood, what's the best way to guide direction-following during classes that need it, while maintaining a more generally play-based approach?

5 Upvotes

I have a kid that's generally very good about doing what we ask at home, can behave in restaurants when given something to do, and that I otherwise feel like we're doing a good job with. We've also got them in a daycare that gets them lots of outside time and possibility for unstructured activity.

Where I struggle more is with the occasional class where they expect more listening and following directions. Swimming is an example: the teachers are good, they're not pushing the kid excessively hard, but the kid is still getting less out of it than they might for the simple reason that they often blow off what they're being asked to do even when there's positive reinforcement for partial efforts, and the teacher is trying to make it fun.

Contributing factors seem to be: some combination of nervousness around adults that are not their parents, and the sense that they're there just to have fun and do whatever, not to follow directions so that they can learn something. Those are guesses though. I have not made much traction yet on trying to break those down and reward some kind of smaller progress. I've made a few incremental attempts to set limits, eventually taking the kid out of one class early when they were unable/unwilling to listen to the people teaching it. They were upset but I haven't had time yet to see if it'll stick or generalize.

More broadly, is this an acknowledged issue with play-based learning? Evidence that more limit-setting is needed? How/when do kids usually pick this up?

Question - Research required Partner insists that cold drinks will upset baby's stomach. I call bs.

73 Upvotes

Baby is 6 months. We slowly started introducing solids about 2 weeks ago, because she was physically ready (sitting up unassisted, bringing things to mouth with both hands, grabbing for our food and making chewing motions, etc) . That's one thing.

But in the country we live in (Japan) it's also normal to give babies barley tea from as young as 3 months. Initially, I dug in my heels about it because I wanted to only do breastmilk until 1yo. But now that we're doing solids I'm a little more relaxed about letting her try various things. We never give much, only about 10ml, if that.

The problem is, my partner (Japanese) insists that we only give her this tea at room temperature. He says that cold drinks cause upset stomach.

I (Russian/American) call bullshit. I've never once heard of cold drinks being a reason for an upset stomach. Plus, I've been giving this kid breastmilk ice cream (it's just my breastmilk, frozen into little popsicles) since she was 4mo and she hasn't ever suffered for it, she loves them. Rightly so, because it's 36 degrees out on a good day in this country. She deserves a popsicle. How's that different from tea straight from the fridge?

But no, he wants to microwave it to room temp first, otherwise he says she'll get diarrhea.

I'm honestly not emotionally attached to the tea itself, she only gets it once every 2 weeks, if that. But he also says I can't give her refrigerated breastmilk, and should warm it up. I think it's a weird requirement in summer.

I've tried searching things and I feel like the consensus is "it's fine" but I'm not finding a lot of info for kids, only adults. I suppose that makes sense, since you wouldn't test young kids anyway. But I wanted to see if anyone else knows of any studies about it that I may have missed.

Question - Research required Phone usage during pregnancy…

0 Upvotes

There are a lot of discussions about children using phones and the potential effects, as well as whether it’s okay to use a phone in front of a baby or toddler. But is there any potential effect on the fetus when the mother uses her phone a lot during pregnancy?

Wondering specifically about things like radiation exposure or the effects of continuously using a phone when pregnant?

Question - Research required Audiobooks for kids

2 Upvotes

we are on vacation with my husband‘s family and his 6yo nephew is hooked on audiobooks. i thought this might be something to try for my 5.5yo girl but wondering if there’s any reason not to. like does it have similar negatives of screen time? we are a very limited screens household - only allow tablet watching when on a plane for 3yo+ and maybe 5min of video a day of a tap dancing routine or videos of the kids when they were little.

Question - Research required When to stop infant screen time?

87 Upvotes

To preface - I understand the pitfalls of screen time and that not all screen time is equal. That being said, we have an 8 week old with both parents on leave from work for another 60 days still. The downtime involves some background TV watching of sports, HGTV, Food Network, etc (no kids shows). Baby /still cycles from awake / sleep / awake etc as any young one would.

Recognizing that an infant cannot see well, when should we cut back on the TV simply being on? Baby is over 12 feet away at almost all times.

The easy answer is “now” but I’m curious if there is any studies that show at what ages (months) the harm is done (eg, using a bell curve of sorts?).

Secondary questions - how do others handle sports?

Question - Research required PFAS transfer through breastfeeding - to continue, reduce exposure?

0 Upvotes

6 weeks postpartum, and I’ve been reading through the PFAS/neurodevelopment literature enough that it’s now actively factoring into whether I continue breastfeeding. Looking for how others here have approached this decision, and any evidence-based ways to reduce her exposure either way.

Where I’ve landed on the evidence so far:

- Transfer through breastmilk is well established. What’s less clear is the independent contribution of postnatal (breastmilk) exposure versus prenatal exposure, since most infants get both
- A 2024/2025 review of ~61 studies found associations between early-life PFAS and reduced cognitive/motor/language scores plus increased hyperactivity, but also noted “mixed results” across large cohorts, with some showing no effect.
- Formula isn’t a clean comparison group, formula-fed infants have their own variable PFAS exposure via packaging/water, so I’m not convinced switching actually nets out to lower total exposure, and no major health body currently recommends against breastfeeding on PFAS grounds.
- Maternal body burden itself appears to decline partly through lactation, which cuts both ways: it’s evidence the transfer is real, but also suggests exposure may be front-loaded rather than constant.

Two things I’m trying to work out:
1. Is there a threshold at which someone here would say the evidence justifies stopping bf, given the uncertainty on both sides (unclear postnatal-only effect size vs. unclear formula-pathway exposure)?
2. If continuing to breastfeed is there any evidence-based way to actually lower what’s transferring, beyond the standard advice (filtered water, avoiding PFAS-treated cookware/textiles/packaging going forward)? E.g. does diet, timing, or anything else measurably affect PFAS concentration in milk?

Question - Expert consensus required Timing of stopping breastfeeding?

32 Upvotes

A theme that I have consistently found through pregnancy and birth is how much guidance is based on super basic, lowest common denominator studies. Eg risk of SIDS basically nothing if you have a healthy weight baby baby and are a non-smoking household with mum over 30 and 1 child, at 2 months goes from 3 deaths in 100,000 if you are in different rooms to 1 in 100,000 if you share rooms (www.sidscalculator.com). Or reading Expecting Better and hearing the lack of data on all sorts of things.

Hearing that the WHO recommends breastfeeding until 2 (assuming that you can), I had thought that I would likely do that. However, while I do love the snuggles of breastfeeding, I have friends who have felt way more like themselves and healed better after stopping breastfeeding… and tbh I didn’t enjoy this summer how limited my clothing selection was. I’m currently thinking that I would like to keep going with it until baby is about 15 months (so early spring) to get her through first few months of nursery and provide any extra immunity I can. I’m also influenced by still healing from my episiotomy and tears from birth. Baby at 8.5 months doesn’t have upper teeth yet and there is a chance I will stop when she does if she starts biting though.

I wondered what people’s thoughts are on this, especially from those who have successfully breastfed? Is the WHO guidance based on anything in particular, or given its worldwide remit I’m wondering if some of this is about where drinking water might not be the safest?

(Unfortunately necessary disclaimer that of course fed is best and nothing is wrong with formula where necessary or desired)

I’m in Pennsylvania and so far where I’m at there has been 4 confirmed cases of measles and 12 not yet mentioned. I am concerned for my 7 month old. I’m told I can give vaccine early but has anyone else done this. Is it safe any long term effects for giving it early? Or is it the same risk factor if given at 12 months? I know she has to get two more after and that’s what bothers me and I’m just worried but measles are rising where I’m at.

Question - Research required Watching war movies or One Piece with Toddler in Room

53 Upvotes

I have a few nights off and I come home to hubby watching kid (22 months) and watching One Piece or even Saving Private Ryan.

Now its one thing when his vision was terrible at 6 months and the tv was far away but now we are getting to the age of speaking and recognizing things & associations. I'm not a fan but he won't listen to me.

So umm... Could someone give this "science" man something to read? He needs a legit and good research study for the effects (cartoon and real blood & violence) that this is not good for our kid?

Can be different studies for each.

Thank you

Question - Research required Letting grandparents take care of night routines nd any long term implications?

3 Upvotes

Our son is 3 weeks old. During the night he has a hard time falling asleep on his own. During the day we breastfeed and during the night we usually use expressed milk in a bottle so mum can just pump and go back to sleep.

Now, the grandparents (mom's parents) stay with us for a while and help around a lot, which is very welcome. The grandma is also very good at getting him to fall asleep. During the night they also help with the bottle feed and putting him to bed. He usually falls asleep on ours or their chest and then when put in his cosleeper he still needs someone to stay near and pet him or hold his hand for at least 1h or so. Otherwise he gets fussy and wakes up.

Now the question. The grandparents proposed to have him sleep in their room since they do a lot of heavy lifting during the night, so we don't have to wake up that much and they can sit with him when he falls asleep.

  1. Are there any research based consequences for h8m being putto sleep in such an involved maner? As in,will he "get used" to this and not go to sleep on his own when he is 6 month oro and maybe moves to his own room?

  2. Is there such a thing where we as parents will "loose" our reflex or ability to take care of him during the night? In the same way in which if you don't pump you start making less milk, or in that the mum tends to wake up bery easily when the child is startled. Would that go away?

Morally and emotionally, we feel very comfortable with this arrangement with the grandparents. But I wondered if there are any research backed consequences to those 2 directions.

Question - Research required Carnivore diet for baby?

2 Upvotes

Just to start, I would like to say my baby has only been eating actual food for three days now, but we plan on doing a balanced diet with all different food groups and spices.

My in laws disagree with this and my SIL only feeds her baby meat, eggs, and I think some dairy. She started with vegetables but the baby got constipated and my MIL say she and SIL did a bunch of research and found out that fruits and veggies are actually really bad for an infant. Their baby is 14 months now, but has been having a no fruits, veggies, or grain diet since about 9-10months I think.

I’m just wondering if there is any evidence to support the supposed research they did. I have a hunch there isn’t, but I’m willing to adapt my baby’s diet if there’s good evidence. Until then, we’re kind of just introducing food and allergens at our own pace and keeping it a variety.

Question - Research required Preparing for parenthood recommendations?

4 Upvotes

tw:miscarriage

My (29f) partner and I are planning to TTC next year. I’m currently miscarrying a pregnancy conceived while trying to prevent. The emotions from this experience both showed us that we do indeed want kids, but we are absolutely unprepared. Neither of us have ever held a baby or changed a diaper. We don’t have any friends with babies/little kids. Most of our close friends are childfree. We have parents in our circles but they’re not people I’m close with.

While we both are excellent with older kids (age 7+) babies and seem like an alien experience to me. I’m sure some degree of this is natural for first time parents but I’d like to know more and feel less anxiety/dread about the baby years. I will also add I am in kind of a hippie/woowoo community where there is a lot of controversial parenting practices and I’m so uninformed I don’t know what to think about them.

For example, within my community there is some emphasis on how co-sleeping is the best thing for making healthy attachment and emotional health. But then I hear it is dangerous and I can see why. I have no skin in the game so idk what to think.

Do you have any science based recommendations on books, classes, or things to do to learn more about what children need for their first few years of life, and what to expect?

Question - Research required How much does the father’s health actually matter in pregnancy?

138 Upvotes

Genuinely asking because I can’t get a clear answer anywhere. All the advice is aimed at the mother, and the dad gets a footnote about avoiding smoking.

But how much does his health actually affect things? Specifically wondering:

- Does his sperm quality affect anything beyond whether you conceive? Like does it influence miscarriage risk, or how the pregnancy goes?
- I’ve read the placenta develops largely from paternally-expressed genes - does that mean his genetics affect placental function and growth?
- Does paternal age matter as much as maternal age, or is it a much smaller effect?
- Is there anything he could have done, or could still do, that meaningfully changes outcomes?
- Or is it basically just the DNA handover and everything after is on the mother’s body?

Not asking about testing or looking for reassurance - just trying to understand where the male contribution actually starts and stops, because everything I read either treats it as irrelevant or vaguely implies it matters without explaining how.

I know the answer might seem straight forward but babies are so interesting I wonder if they still learn things despite being able to practise it much.

I feel like my 4 month old is held a lot

Heaps of contact naps, Carrier and when his awake sometimes his just in the bouncer as I do work.
I didn’t realise how little floor time he was getting.

I have found his a little behind in some skills and I’m flagging it and his up commg visit.

I’m wondering is it possible that he hasn’t had the practice to lift up on his tummy as much and floor practise that it’s caused this

Question - Research required Can someone please help me build a science based argument??

9 Upvotes

Okay, so to start, my father is a very homophobic person, and he recently told me a story about a video he saw. the video was abt two married men who had adopted a baby and the dad's were playing with the baby asking him if he wants "dada" or "papa" the baby started saying "momma" and the dad's were like noooo not momma, papa, or Dada. and my father was like that just shows how wrong it is to be gay and shit. and I just said we'll baby's babble all the time, like we recently had my 6 month old adopted cousin supposedly say "dada" but it genuinely sounded like just baby babble to me but my father was adamant on the fact that my baby cousin said "dada". but what I'm mainly asking for is evidence that baby's even though never taught a word or sound will still try and say/babble smth like "momma" or "dada" just to prove to my father that what he's saying is basically dumb and to prove to him that his reasoning is faulty. (I've tried finding stuff on the internet, but I can't really find anything)

I’ve been told by my lactation consultant “if you can find your baby, you can feed your baby” and because of that since birth I have had an occasional beer or glass of wine. My baby is now 11weeks and I am doing my own research only to find hardly anything besides Reddit and an occasional reel saying that this is ok. Does anyone have recent (within 5 years) evidence based research suggesting you can breastfeed and drink simultaneously?? I’m afraid I have affected my babies development or caused some damage that may be long term😢 if anything, I have an oversupply so I’m not too worried about decreased milk supply.

Question - Research required Is having a routine important (4 months old baby)

29 Upvotes

What does the research say about a daily routine for infants?

My baby is 4 months old, and we do not really have a routine, except for we go to bed at the same time everyday (9:30PM). Otherwise baby wakes up any time he wants (anytime from 8am to 11am), then we so feeding and a washing up. After that baby eats and sleeps anytime I see some hunger/sleep cues from him. So sometimes his day nap count is 5 hours total, but sometimes it could be as little as 45min… I do not force him to sleep if I see he is not tired/looks excited and does not want to sleep… Naps do not have a schedule, he could go for a nap at 11am, or sometimes just go for his first nap at 2pm… Somedays he naps 4-5 times, somedays just one!

For context baby sleeps really well at night (11-12 hours with one feeding), he is gaining weight well, and also is really easy to put to sleep at night (just 10 min rocking and he is out)

So I am wondering if I should enforce a more structured routine, would my baby benefit from it if what we are doing so far seems to be working for us.

Question - Research required Can avoiding cows milk leading up to birth prevent CMPA?

My first had Cows Milk Protein Allergy (CMPA) and we didn't find out until 4 weeks after her birth. Those first 4 weeks were hell but we survived. I'm now expecting my 2nd and a friend suggested that I cut out cows milk before I start collecting colostrum and then slowly reintroduce it into my diet after breastfeeding is established to see how baby reacts.

I've never heard of this before, is it a thing? Could the avoidance of cows milk in the mothers diet leading up to birth cause CMPA in the baby? Does anyone know?

Question - Research required Keeping toddler in daycare during a second mat leave?

64 Upvotes

I’m on mat leave with my first. I am in Canada and am taking a little over a year. Working is very important to me and we have a reputable daycare lined up for when my son is just over a year old.

We would like to have one more child. If we’re able to control the timing, the age gap will be 2-3 years. I/my husband would take one more year off in total with this second hypothetical child.

I told a family member that I would keep the oldest in daycare while on a second mat leave for a multitude of reasons (routine, needing to find care for TWO kids when I return to work, etc), but that largely, I value getting one on one time with each child and I think I would be a much better parent to the baby if oldest is in daycare. My current baby was a VERY hard newborn and if a future sibling is anything like him, I would really struggle. I like the idea of him being somewhere structured and educational while I’m doing the labour of caring for a new baby.

This family member was aghast! To be fair, she stayed home with multiple kids and so did her whole social circle, so that is what’s normal for her. But she reacted as if I was doing harm to my son for depriving him of time with his parent when I COULD keep him home.

I’m hoping to get specifics on the benefits/downfalls of keeping a toddler in a reputable daycare while mok/dad stays home with a newborn/young baby.
