Bedwetting Pants While not completely waterproof, these are worn over pajamas to prevent the bed from getting wet. I used them as insurance when my child slept, but since they didn't wet the bed, they ended up replacing a belly band and a blanket. They've been washed several times, so there's some fuzzing on the line of the bottom button. Please refrain from purchasing if you are sensitive to items that have been stored at home.
