Daughter is 6 months and tries realllly hard to roll from back to front.

She arches her back and go to the side but just can't kick her leg over or figure out how. We've tried practicing with her we used a blanket to show her the movement. We've done everything and she just gets so frustrated every day that she tries and can't.

She has almost a tantrum after she tries to do it and then kicks her legs down really hard and then cries. She's done this For a few weeks now and I just don't know how to help her lol

She can sit up unsupported for a couple minutes now, she knows how to scoot around to get her toys. She just can't roll over no matter what. Any advice??
