I dont think its gonna happen
My baby is never going to roll from her back to her stomach. Never. She learned at 5 weeks old to roll from her tummy to her back because she hates tummy time so much. It is impossible to get her to stay on her tummy. Now that she is almost 5 months old, sometimes shes already trying to roll to her back while shes still in my hands when i try to position her for tummy time. She will roll to both sides from her back, but I think she hates being on her tummy so much that she will never roll to her tummy lol. I bet she will skip crawling and just pull herself to stand one day.
