We are are visiting soon from the UK, and were planning on buying our son's swim nappies in the US, rather then bringing our own supply with us. We are staying in a villa with a pool and the second week at the beach with a pool so I am sure, knowing my son, he will be in water longer then on dry land! The type of nappy I mean is a disposable nappy that is worn under normal swim shorts which is made specifically for swimming (UK version is Little Swimmers by Huggies). Could anyone tell me how easy it is to get hold of these? We will probably be doing our grocery shopping in somewhere like Walmart or an equivalent supermarket near where we are staying (Kissimee) so wont be going to any special baby shops etc. Do all these types of supermarkets sell swim nappies or would it be safer to bring our own supply?
