4 month sleep regression

[eed32]

Hi all, we are in the depths of the 4 month sleep regression here at 17 weeks with our little one, pretty sure its been going on for nearly two weeks now but this week has got far worse, up every 45 minutes throughout the night. Prior to this I nurse my little boy to sleep everytime and he always slept super well in his next to me crib and from about 8 weeks old slept through the night.
we have made the decision not to sleep train and not to change the sleep associations we have created, I.e. nursing or rocking to sleep. We also don’t wish to co sleep. I appreciate online says sleep training is the only way to get your little one to independently sleep etc but we’ve made the decision not to do this. My little one has been nursed to sleep since birth and would self soothe by sucking his thumb when he reached about 2 months old, I believe he can self learn this again if I am patient and give him time to do so.

My question is, did anyone on here not follow a sleep training plan or change from nursing/ rocking to sleep and have success with it? I.e, baby’s sleep went back to okay/ normal after the regression?

I think you have to decide whether you are happy to nurse to sleep that often and if so, for how long, because it might change... Or it might not. If you aren't happy then you have to find another way to settle the baby - that doesn't mean leaving the baby to cry, it just means comforting by other means. Around that age, my partner started to do settles at certain times - so if the baby had fed within the last two-three hours, DP would use a shush-pat approach to soothing. Then once I was confident the baby was hungry again, I would do a bigger feed that would send the baby back to sleep for another longer stretch. We partly used this method because feeding my baby led to needing a nappy change and we didn't want to be doing that every 45 minutes. What that looked like was a last feed around 9pm, then 2am, 5am, 7am.
