DS is 3.5 mo and has mastered rolling onto his back. He can't get back again which we are working on but he likes being on his tummy so doesn't have much incentive!
The problem is he gets frustrated because he seems to want to move forward but doesn't know what to do and then he gets upset. At the moment he lifts all four limbs and his head up off the floor and looks expectantly like something should happen...
I would just put a toy in front of him to play with but he's not too interested - I can tell he wants to do something active when he's down on the floor.
Does anyone remember what their babies did after they learned to roll but are a long way from crawling?
