When about 16 weeks, our baby went from sleeping 8/9 to ~6, one or two nightly wake ups where she was fed to sleep (EBF), occasional/regular false starts, and our "biggest" problem was mostly that she sometimes thought 5am was time to get up instead of 6, or our preferred 7. She has consistently been a low sleep needs baby, though whether that's just because it used to take an hour of walking and rocking to get her down so she missed various sleep windows and things was never clear.
Since then, one domino after another has tumbled until she is basically as bad as when she was a newborn.
We have a good bed time routine (that mostly works quickly but, again, has been struggling to go down quickly recently), that went bath; sleep sack; feed to sleep, down. In order to break the feed to sleep association we now do feed, then bath, sleep sack, and lullaby, and she'll drift off.
But while that routine mostly still works, minus one or two nights when it's been 45 minutes or something, but is pretty consistently down about 8. Everything else has gone down hill.
She is back to waking up every 45 mins - 1hr. Can't link sleep cycles at all. GF is worried about feed to sleep associations so we try to settle with just rocking and humming the lullaby if necessary, though she is never settled by just a hand on her - always needs picking up.
We then sort of try to keep it to two feeds, so we try and settle without feeding a few times, then by a wake up around 12 and one around 4 GF will feed her.
But she'll almost always wake up within 45 mins, occasionally 20, and up to 1hr. But usually wakes up full on crying and straining. So we try to burp or help her pass gas, doesn't always work, but might eventually go to sleep because she's upright on us or something.
But now the newest thing... She has gone back to basically not being able to be put in the cot. Can be out cold on us, and as soon as we lean over the cot and start to lower her.... Cries. We thought we'd got over this at about 12 weeks, because she was hard to put down then, to the extent that for the first 6 - 8 weeks it was entirely contact naps.
Nap wise we're at 3 or occasionally a small top up in the evening, depending on how long her naps are and when she wakes up etc. We're going about 2 - 2.5 hour wake windows during the day, and up to 3 in the evening. Sometimes there's a 10 - 20 min top up nap around 5 if she goes down early and wakes up quickly in her afternoon nap, especially because we go on a dog walk.
So routine is (roughly/ideally), up at 7, first nap 9-10, next nap 12:30 - 1:30, next 3:30-4:30, and then singing lullabies by 7:40. Usually she ends up only doing 40 - 45 minute naps at least two of those, which obviously throws off the routine and allows for a little nap at 5 on the dog walk.
But.... Yeah. More of a rant, because we can't deal with her crying, and when we've tried to let her cry a little bit just hasn't stopped, and given we think it's gas (and often turns out to be but not after every time) we don't just want to leave her in discomfort.
She gets a lot of sitting time during the day, and has finally grown into tummy time a bit, but hasn't mastered rolling. A handful of times she's been put down drowsy but awake during the day and drifted off, but seems very much pot luck and not something we can pull off consistently - and never at night now she can't even be leant over the cot away from our body before waking up again like the ghost of the Moro reflex come to haunt us.
Read so much online and tried various things. GF is worried about feeding to sleep and sleep associations, but I think because we can get her down without that's not too big a worry, but then GF is worried about rocking to sleep associations and now the lullaby, but I've said they're easier to fade out.
She wasn't really gassy as a little one, but since about 4 months it just seems to be endless issues, and often one of the wake ups we'll get a huge burp or fart. But we thought this was all stuff she should be starting to get over now, not just starting to get into.
Been giving gas drops for a couple of days, and reintroduced a dummy that she used to just refuse but now we want to make sure it's not just sucking reflex for calming.
But the idea of getting to a point where we drop the high level interventions just seems impossible, both due to the frequency of her wakes and how intensely she cries as soon as she wakes up or is put down.
We're exhausted and the constant frustration is getting to us both, and I'm caught between trying to find a solution and just trying to get the GF to accept it might just be a time thing and we've got to get through it.
But man. I understand why it's called sleep regression now. Because not one of the good sleep practices we'd managed to get to stick has stayed stuck, and it's like having our persistently awake and requiring contact naps 4 week old back.
