Babies Who Sleep on Their Belly?!😴

My almost 6 month old has always been swaddled until about 2 months ago when she constantly started rolling. She usually has been a back sleeper/sometimes side until recently. Every time she wakes up at night it seems that she is on her belly and trying to play/get up. She does like to sleep on her belly but for the most part it seems to wake her up! Anyone else have this problem? I've even tried laying her on her belly first and right away she's awake😐
