DD is one week shy of 3 months old. Until now, she has co-slept with us. She hates sleeping on her back. She'll wake up as soon as I place her down on her back. For that reason, I have been letting her fall asleep on my chest (bad, I know but desperate times call or desperate measures!)

I am as ready as I'm ever going to be to transition her to sleeping in her crib in her own room. How do I train her to sleep on her back? Also, how do I train her to get used to her crib for naps/night time sleeping?

FWIW- I will let her take naps on her tummy since he has good head control. I just watch her like a hawk during.

Any help would be SO appreciated!
