Baby rolling but upper body not strong

I help train my baby when she start learning how to roll over. Like not entirely help her, just give her a little support while letting her hold onto my finger while she does the rest herself.

My 7 month baby can roll easily and she’s still frustrated 🤣 Maybe some babies are grumpier

able to roll means the whole baby body can turn over like sideways or roll 360?

when you do TT, can your baby whole body up?
