They do allow them.
Caution with floaties: My grandson, age 3 and skinny 🙂, used an "inner tube" type floating device "for extra safety precaution" in the kiddy pool. Somehow he flipped over with his face in the water and was unable to right himself due to the position of the tube above the water. Mom was close by and helped him up. In that case the flotation device created more danger than protection.! He may have been too tall for that size tube. Just be cautious .
Air blown ones?
