When my DD turned 4 months she stopped STTN. She goes to bed much earlier, before it was 11pm but now she goes to bed 9-9:30pm and wakes up around 3am. She will be looking around or sometimes will cry. I let her try to go back to sleep but it doesnt work, so I change her diaper and nurse her and she will fall back asleep. How do I get her to STTN again? I told DH that we might need to sleep train her since its an ordeal to get her to sleep. She needs to be put to sleep and I would love for her to STTN and wake up around 8. Any advice?
