Ds has just turned 6 months old and has recently learned to roll from his back to his front which he likes to do all the time! The trouble is once on his front he doesn't seem to be able to get back onto his back and after a while ends up whining for help! He did roll front to back a couple of times when he was around 4 months but they were more a fluke than anything and he has never been able to reliably do it. He enjoys tummy time and can lift himself onto his forearms/hands when on his front, and if he is on his side he can easily flip himself onto his back so he gets that part of the motion. It's the initial part he is reluctant to do, he just makes himself into a stable little tripod! Are there any ways I can encourage him to learn so he doesn't get himself stranded?
