Matilda slept on her belly from 12 weeks old. We were at a sleep school at that time & no one was able to get her to sleep on her back & she decided she would be fully able to roll back & forth at that point. The nurses & paediatrician there said that because she wasn't in any of the other "risk" categories to let her do it. It was the only way she would sleep until she was 14 months old. Everytime we rolled her onto her back or side she would wake up.

I was nervous for around 2 months and stressed about it heaps, but in the end I gave up trying to put her into a different position and just let her sleep that way. We used a sleeping bag for her at that age as well but made no difference in her rolling abilities either.

Goodluck Linda!
