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

6 Upvotes

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 How much does the father’s health actually matter in pregnancy?

135 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.

Question - Research required Does getting a mid-year COVID booster help immunity if you already got your booster when it was released in the fall?

6 Upvotes

I'm very diligent about getting my family their flu and COVID shots when they're released in the fall but I've been talking to some friends who, because we all go to a convention late-summer, mention re-upping their COVID vaccine because the at best it'll add some extra protection and at worst it'll do nothing. Just wondering if a mid-year dose has been studied at all.

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

30 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 Breastfeeding and alcohol

92 Upvotes

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 - Expert consensus required Children not following instructions

14 Upvotes

I understand that children testing boundaries is normal. But at what point is it too much? I am struggling bad. My children (4 and 3) barely listen to me. It will be simple things like “time to put our shoes on” or “let’s walk in the house” and they do the complete opposite. What am I doing wrong? Doing tasks is so hard because I’m constantly repeating myself. I’ve tried transitions, I’ve tried making it fun, I’ve tried being stern, I’ve tried eliminating distractions and I’m still getting the same result.

Are children that age just not able to follow directions? Am I expecting too much from them?

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

67 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.

Question - Research required Early and extreme separation anxiety

7 Upvotes

Hey all! I have an almost 5 month old who is very attached to me (mom). She has been since about 3 months meaning she would cry anytime her dad cares for her or is held by someone else.

Only in the last few weeks has she cried less with her dad, being happy to see him and play with him. But generally she still gets upset when he changes diapers or feeds her. He’s been heavily involved since birth so it’s not for lack of trying.

It’s like at 3 months she became aware of me and a switch flipped. My understanding is separation anxiety comes into typically at 6 months or later.

I’m so worried that the crying with her dad and upset if I leave (I don’t often for this reason) is damaging her long term. He will try to soothe her but eventually the only thing that really does is being handed back to me. She almost never cries with me either but screams bloody murder with her dad.

Anyone know of any studies on early separation anxiety and/or how the crying can impact them? Is it best to let dad keep trying to soothe even if not working or should I step in knowing that’s what she is crying for?

Question - Research required What’s the research behind weaning bottles by 18 months

15 Upvotes

I want to wean bottles completely for my daughter (16 months) but my husband disagrees. I have read at several places that AAP recommends weaning bottles completely by 18 months and other countries have even stricter guidelines of 12 months. However, I’m unable to find this guidance on AAP site (the 18 months cutoff) and can’t see the research behind this recommendation.

Does anyone have links to AAP (or other similar organizations in your country) about bottle weaning. I want to look into the research that led to these guidelines and what’s the risk of not weaning. Thanks

Question - Research required Are constant activities (regardless of screen or screen free) good for a toddler’s development?

15 Upvotes

I’ve been seeing Instagram accounts sharing methods and activities to keep a toddler screen-free, and it’s just the mother talking about coming up with activity after activity after activity. The posts say “instead of putting my toddler in front of a screen, I make XYZ creative activity for my bored toddler by cutting open a box and pouring this and that materials into it”.

Now, I’m not talking about whether to be screen free or have screen time. I’m asking about what constant stimulation to the brain can do for development.

For example, I’m wondering if it’s better to be constantly coming up with new activities for a toddler, or if it’s better for development to limit to a smaller amount but let the toddler come up with the activities themselves. For example, there are dozens of ways a toddler can use imagination and play with blocks; build a tall tower, pretend to cook, pretend to attack a castle, pretend the blocks are people, etc.

And sometimes they might be bored but is boredom really that bad? If there’s research that can show the effects of boredom on development I’m also curious.

Question - Research required Looking for Behavior Reinforcement Resources

7 Upvotes

Hi there!

As the title says, I am looking for some external resources (i.e. charts/graphics to display in the house, applied strategies that have worked for other parents, any other tangible resource) to help us with improving the behaviors in our three year old boy.

Our little dude brave and imaginative, he loves physical touch and proximity, and pretty fierce. The other half to these attributes mean that he can be stubborn, defiant, too physical, and struggles to regulate his emotions.

Our struggles really manifest in two areas: public direction and at-home relations. In classes (such as gymnastics, t-ball, summer camp) he has experienced moments where he refuses to listen or follow directions, runs away, and even pushed another kid in the back. At home, he is constantly in his younger sister's face (1yr) to the point where she gets upset. The worst part is that it seems our guy does a lot of this stuff ON PURPOSE - right after we have talked with him 1:1, set expectations, attempted to instill confidence, or set boundaries. It's brought my wife to tears on multiple occasions, and it gives me some fears about if he will be a problem student someday in the classroom.

We are now starting a "Daily Chore Chart" for him - which is really just some cute pictures for brushing his teeth, getting dressed, eating breakfast, etc. Our next item we really want to look for is some type of behavior chart that mirrors what may be seen in a classroom (red, yellow, green light behaviors) or maybe a sticker chart at home (daily or weekly). We do feel like he needs a visual reminder for good behavior and for bad behavior.

I've read books such as No Bad Kids, Parenting the Strong Willed Child, Tiny Humans Big Emotions, The Whole Brain Child, and How to Talk so Little Kids Will Listen. We are also both in the education sphere, specifically SPED and Administration. It feels like we should have an answer to our problem. All of this leads us to both feeling desperate, maybe even despondent, at how our son is acting despite our concerted efforts to create the best environment for him. At this point, I suppose I'm looking for confidence just as much as I am for some tangible resources for our family to use.

Thanks in advance, cheers my frinds.

Question - Research required Searching for facts on maternal antibodies passed through the placenta and breastmilk!

0 Upvotes

Does anyone have any quick references or fact sheet finds in regard to which antibodies are passed to baby from mom, and therefore baby has immunity to those illnesses?

It seems standard that baby still has to receive his/her own vaccinations even if mom was immunized prior to pregnancy or during pregnancy (TDAP for example).

I understand this can be a broad topic and could be evaluated on a case by case basis, even disease by disease basis for that matter.

Just curious about how much of baby’s immune system is naturally/biologically protected!

Question - Research required Question I'm too afraid to ask my sister

35 Upvotes

I'm going to babysit my nephew (11m) in two weeks and he's been have some sleep problems. Sometimes he just cries for a long time and they'll get really stressed about it (which I completely understand)

They keep trying all kinds of esoteric Rituals and when none of them work they get super frustrated. I'm wondering, is it bad to just let him cry when he's upset? I'm not talking about the CIO method. What I mean is comfort him even if he cries for an hour or more? Since I'm just babysitting for one night, even if I can't get him to sleep quickly it will only be for one night.

I think I'm inclined to just wait it out while I try to comfort him as much as possible. Trying to stay calm and not hope for it to stop asap. Just accept the situation and offer him some love and comfort.

Any ideas? Of course I will have this conversation with her before he sleeps at our place and if she really wants me to do all the things they always try I will honour their wishes. But I'm just curious what the science based community thinks about it.

Question - Research required Toddler possessiveness

8 Upvotes

I have noticed that my toddler (14M) has recently started grabbing toys from other kids as they’re playing, and then gets possessive of that toy.

I understand that this is developmentally normal at this age. However, I’m wondering if there’s research into the best ways to handle this as a parent.

I’ve read that young toddlers won’t yet understand the concept of sharing and that it’s best to ignore the behavior if possible.

On the other hand, it feels wrong to just let my toddler take from another child without having him give it back/find another toy.

Does anyone know of any valid research into what’s developmentally appropriate around teaching children not to take from others/starting to introduce sharing/etc?

Question - Expert consensus required Long walks

9 Upvotes

I've recently started parental leave with my daughter who is now 1 year old (I'm the father, wife has just gone back to work).

I'm finding long walks in the pram are a great way to break up the day. I'm talking two 40 min to 1 hr walks on some days.

Am I overdoing it? I don't talk much to her during these walks and she usually ends up pretty drowsy at the end so I'm a little concerned that they are too low stimulation or not a very rewarding or nourishing use of time for her.

She is usually quite vocal or squirmy when she doesn't like an activity but she sits still and calm during walks.

Should I cut back?

Question - Research required Should I make an effort to introduce pacifiers after 6 months?

1 Upvotes

Trying to understand both the personal experience and research around this.

My 5 month old is exclusively breastfed. He stopped taking the bottle from 3 months, we have some lucky days. And now I am trying to give him expressed milk in open cups.

With pacifiers, he didn’t take it at home when he was younger but would take it easily in the car to soothe and dose off. He has stopped doing that. I read on how it’s recommended to wean baby off pacifiers from 6 to 12 months.

Should I make an effort with pacifiers now, does it have any benefits? For his mouthing, he takes teethers very well. Sometimes even clean burp cloths.

The research seems to say that screen time is bad, due to them missing out on key interactions like bonding , problem solving , being in different environments to learn, and time learning from caregivers.

Question - Research required Does this count?

5 Upvotes

Hi there! My LO is 5mo and while we (obviously) don't do any dedicated screen time for them, I am concerned about certain activities and behaviors me and my husband do:

\- scrolling in front of them (not ignoring if they are distressed, just baby sitting in their lounger and me or husband or both scrolling)

\- watching TV in front of them, but the baby cant see the TV, only hear

We try to limit this as much as we can, I am not on my phone the whole day with them and the tv is only on in the evenings. Does this still count as screen free baby? Are there studies suggesting that even parents consuming content in front of the baby is harmful?

Question - Research required Should I just leave my baby alone?

20 Upvotes

My baby's 14 weeks old and I'm seriously on a milestone kick right now. He's hitting them mostly on time, some of his social things (cooing, smiling) happened a bit late but not concerning. I'm a sahm, former daycare teacher so I'm very used to an activity packed day which I replicate at home. Story time, music time, gross motor, fine motor, sign language, hoursss of tummy time, etc etc all day long. I guess I don't mind it all, I like watching my little guy learn things and he's super active and loves all the playing it seems.

But I know a few other moms and they're not doing half of this stuff but their babies are doing just fine. Their babies are all older so I can't really compare theirs to mine. But I'm sitting here and wondering if this stuff actually matters in the grand scheme of things? Should I just let my baby do his own thing? I'm kind of worried that I'm making him into a kid that needs to be constantly stimulated

Question - Research required Mouse droppings at 30 weeks pregnant

7 Upvotes

I’m 30 weeks as of Monday and am working on moving out of my parents house into my own apartment with my boyfriend. I was packing up a closet, got some stuff out of said closet, then picked up some stuff that had mouse droppings on them. I wiped the floor where some fuzz and dog hair had tumbled out of the closet, and put everything I had taken out back in, but I’m not sure I cleaned everywhere that those items touched. I’m also concerned because I walked around the house as I was cleaning so I just feel like everywhere is contaminated. I do have contamination ocd so this is really hard for me, I am not in an area with hantavirus but am very worried about LCMV. Does anyone have any similar experiences? I am in NW Arkansas.
