So my little man was in the Nicu for a few weeks and ever since he has been home he has been sleeping with us. He is 3 months now my question is when or how old should I start getting him to sleep in his bed. Right now he will only sleep in it for like 15 minutes at a time he moves around until he wakes him self up but once he is in bed with us He will only wake up 2 times throughout the night.
