My baby girl is 8 weeks old and I sometimes let her sleep on her stomach (as of this week) ... She will sleep up to 4 hours that way, if on her back she sleeps an hour at a time, if she's swaddled. She's miserably over tired.

I know it's not recommended but she just loves it. She can push herself up on her arms, she could raise her head at birth and she has rolled front to back during tummy time.

I feel guilty but it used to be recommended that babies sleep on their tummies and obviously the human race didn't die off.

Does anyone else let their baby sleep on their tummy?
