lo just turned 3 mo. He's been sttn for 2 weeks and sleeps in his crib in the nursery at night. During the day he's not interested in me putting him down to sleep. He sleeps on me and wakes/ cries if i set him down anywhere. It's ok if he's awake and playing, I'm just talking naps. I used to be ok with this because I felt like he was alone all night (has always slept in his crib), but he's getting heavy and I've got stuff to do (I use lots of carriers). He's too small to cio, but how can I transition him to a nap off of me?
