How many mommas let their little ones sleep on their belly earlier than recommended? My one month old refuses to sleep on his back. I have to rock him to sleep then lay him down. Then he's up every hour or two. If I put him on his tummy he sleeps 3-4 hour stretches. I think it's because he's extremely gassy and when he was in the NICU they let him tummy sleep. What are your thoughts?
