N.S.
We recently had the same question and most of the responses were recommending the healthy baby, healthy habits book which I read and we had a hard time with but with week and week of sleep deprivation when we both work full time finally made us give in. She is now almost six months and the one thing that has made a difference is putting her to bed early (around 6:30 to 7:00 pm) gives us peace until she wakes at 1230 for a feeding; she use to sleep at 0830 but once we moved it earlier she actually slept longer! The ceral feeding, a warm bath, and then feeding her is a routine that has worked for us...good luck!
