Hi, would be great if i could hear your views on what might be going on with my 4 months old DS - and any advice what to do is much appreciated. Basically until last week he was sleeping ok, self-settled to sleep without any problems and woke every 3/4 hours for a feed (exclusively BF) but then continued sleeping straight away (boy, tis sounds like HEAVEN now!!!) . He usually had naps during the day, totalling 3-4 hours. Since last week it takes him forever to fall asleep, both during day or nighttime, and then he wakes up crying heavily after 45 minutes. He has refused to sleep on his back and only calmed down either in the car seat or when being fed (he seems to be desperate for comfort sucking so that is how we spent our nights now) . We have tried co-sleeping but that too only calms him down for max 1 hour...I just dont know how I can help him any more and what the problem might be ...is this just what they call a 4 month sleep regression and he will grow out of it after some time? Is there ANYTHING I can do to help him sleep again? many thanks!!
