Rolling front to back

[NameChagaiiiin]

DD is 7 months old. After lots of frustration and tummy time she can flip herself like a pancake on to her front. The second she hits a flat surface she's up on her front, can lift herself up really well and spins round in circles to get to diff toys etc.
But
She cannot/will not roll to her back. Instead she just faceplants the floor and cries when she's had enough. It's not so bad During the day as I can roll her back or pick her up, but she's started rolling herself to her front in her bed now she's moved to her cot bed from her bedside crib and and waking us up at all hours crying as she is "stuck" on her front.

Any tips/ideas? Do I just need to wait it out? It took her a while to learn how to roll to her front but now I'm almost missing the days where she would stay on her back alot 🤣🤦🏼‍♀️

In addition, any tips on if/how I should be helping her get up on her knees ready for crawling?

Thanks

Yes it's just a phase and you need to wait it out and no, I don't have any ideas in how to help her crawl, apart from placing things slightly out of reach. Sorry

My DS is a few days short of 9 months and has just learnt to roll from back to front whilst he's learning to crawl. He never saw the point in rolling before now but seems to want to learn rolling & crawling at the same time.
He's been flipping himself onto his front at night & during naps but can't turn himself back over so wakes up and cries for me to help. I expect this stage might last a few weeks until his brain stops trying to make him practise when he's sleeping or he learns to roll onto his back.
He hasn't fully learnt to crawl yet but he gets into a kneeling position on all fours and then thrusts backwards and forwards - I call it his pelvic thrusts and sing the Time Warp at him when he does it during tummy time.
I got him learning to use his knees over about 6 weeks of tummy time exercises when he was doing his arm push ups. I started with sliding one arm under his tummy to lift his bum up and then push his feet forward a bit with my other hand to make his knees bend. He'd been doing arm push ups for months but hadn't been doing anything with his legs or hips so I demonstrated to him what his legs could do and he's taken it from there.
I followed tips from Emma Hubbard, an Australian baby physio who posts lots of videos on YouTube.
