Oh ok good i was kinda worried. With my daughter she started rolling over at 4 months old too and her doctor said it was ok but i wasn't sure if that was still ok

Yes, you can try putting him on his back still but if he is rolling over he is fine. My son wouldn't stay on his back at 4 months and his pediatrician said it's fine. He is 6 months now and lays on his stomach.

I think as long as he can roll himself over by himself should be okay. 😊
