Do your kids somehow roll themselves off the bed in their sleep? Put your neglected pool noodles to good use as bumpers that make it more difficult for your kids to accidentally end up on the floor. Simply add a pool noodle to each side under the fitted sheet.
This tip comes from Reddit user RyVal, who says that all you need to do is insert two pool noodles under the fitted sheet on each side of the bed. It may not work if your kid is a heavy-duty roller, but it's a cheap and simple solution that may be worth a try.
