My 9 week old has just learnt to roll onto his front, great. However once on his front he then cries. I guess because he doesn't know what to do and can't get himself back or crawl or whatever. So every time he rolls onto his front and cries I roll him back onto his back but then he cries again and rolls over again onto his front! I'm going mad I've literally spent all day rolling him back again and again!!
