6 Month Old Only Rolling over to Tummy?

My DD is 6 months too... been sitting on her own since about 3m, but started rolling tummy to back at around 4m... she still doesn't roll from back to tummy though. I think I have seen her do it twice, so I know she CAN, she just doesn't want to. She has the opposite problem, hates being on her back (unless she's sleeping) and won't take the time to figure out what she has to do. maybe he is in the same rut... he hates tummy time enough that he is so focused on how angry he is that he doesn't concentrate on moving his arm where it's supposed to be, and gets frustrated.

My daughter is 7 months old. She only sits. She doesn't roll or do anything approaching mobility. She hates tummy time. My son was on the late end of normal for all his gross motor skills, and he is fine now. Sometimes it's hard not to worry and compare with other kids. But I'm just trying to enjoy this calm before the storm, because it's going to be a whole new world once she's mobile.

He does know how to do it - cry and you do the work for him. Don't rescue him. During the day plan some time to get on the floor with him and lay him on his belly and let him learn. Also, I would encourage removing the sleep positioner - they aren't safe especially when a child can move and possibly get stuck.

Show him how and talk to him about it while you do it. A baby has heard the language you speak while in the womb and now for six months. If you want him to communicate talk to him. He may not speak but he knows what you mean. Use motherese. Repeat it three times. "Mama's going to help you get your arm out from under you so you can roll over both ways." So that is before you do it. When you do it talking in a loving voice at all times. And once you've done it say, "There your arm is out from under you and you have rolled onto your back."

this is so normal what to do with that silly arm is hard to figure out. you have to let them struggle to learn :)
