Swim nappies
Swim nappies are a must for swimming with your baby or toddler, most swimming pools insist that anyone who can't control their bowels wear clothing that prevents any accidents escaping into the swimming pool - if there is a accident the whole pool has to be drained and refilled meaning the pool can be out of use for a couple of days.
Swim nappies aren' t designed to absorb urine as any absorbant material in the nappy can weight your baby down, their main function is to contain poo, so the correct size is very important.
