How do you teach a baby to sleep at a specific time? To a 1.2 month old baby. There's no strength left, I can't get enough rest, and I can't even put myself in order, let alone do housework. He doesn't want to sleep at all. Here is our approximate schedule for today (different every day): Slept from 11 pm to 3 am, ate 30 minutes Slept from 3:30 am to 6 am Then he woke up until 4 pm Slept 15 minutes And until 6 pm he was awake.
