My 3 1/2 month DD, has taken to waking all night long, roughly every two hours. it started three week ago when we finally managed to get her to go down early on in the evening, about 6.30, she is so exhausted by then, she absolutly needs the sleep. The downside is though from about 11.00pm she wakes almost every tow hours, wants to feed, have to admit she might re-settle with lots of effort and not feed, but 3 in the morning knackered, cold and dark...you know the feeling. She will also not settle straight back down after feeding, keeps waking. result is I have not slept for more that 3 hours at a stretch for three weeks! Please any support advice would be much appreciated. She is breastfed, wanting to perhaps introduce formula feed at night, but currently she is refusing bottle, bottle boot camp starts this w.end!
