My 7mo DD just will not roll. She's been trying for AGES and now just lies on her back waving her arms/toys around. She doesn't play with her feet either unless she's sitting on my lap. She does grab stuff if she's really interested in it, pass from one hand to another, and we started BLW with some good results so far. She's a chatterbox and seems to be doing well generally but this lack of movement is really worrying this FTM! I want to relax because I do know she'll do it when she's ready, but she seems to be so behind other babies we know with no sign she'll do anything anytime soon! Will she still be lying there when she's 5???
