Falling out of bed

Any good tricks to keep your toddler from rolling out of their toddler bed? We have a body pillow on the floor so when she rolls out she doesn’t even wake up and has a soft landing but it’s annoying to have to put her back. She’s in our room and so when she falls out it wakes me up 😂 I’m trying the pool noodle under the sheet trick today, but if anyone has other ideas let me know!

UPDATE: pool noodle rolled up in a blanket and tucked under the fitted sheet has worked great so far!
