Baby practices rollover at night, sometimes faceplanf

She has been rolling for two days now and today at 4am I caught her trying to rollover while I was asleep. She just started to roll so sometimes she would faceplant and didn’t recover for a few seconds.. My question is, is there any way to rollover proof her bassinet? I put her bassinet next to me but I fear that while I was sleeping, she tried rolling over and couldn’t go back because the bassinet is rather small. I am afraid that she might end up on her face. Please advice, thanks!
