Can anyone share any advice/experience - my 4 month old is still yet to sleep through the night and still wakes every 2-3 hrs every night like a newborn. I've noticed a lot of people saying that their babies have regressed at this stage but my LO hasn't ever even got to that stage in the first place, just doesn't seem capable of it! I'm exclusively BFing but tried a big bottle of formula before bed last night but even that made no difference. I had him settled inbed by 9 but then he was up at 12 (till 1), then again at 3, 5 and 7. He doesn't take long naps/sleep excessively during the day and we've even tried leaving him to cry it out several times but he gets himself worked up into such a state we always end up picking him up and I feed him again (we have a daughter so also reluctant to leave him too long not wanting to disturb her!). Any suggestions gratefully received!!
