Hi there, 1st time posting but really need some advice. Dd is 25 weeks, started to wean but she has never slept through night. She used to go down for 4-5 hours but recently max is 2.5 hrs, but she always wakes after first 45 mins. I'm bf and trying to put her down drowsy but not asleep but nothing working. Also have 3 yr old ds so don't want her to wake him by using CIO. Family asking if she is hungry or just waking, but not sure how to tell..she always feeds if offered. Should she still need night feeds?
