We were planning on buying our son's swim nappies (eg. like Little Swimmers by Huggies) in the US rather then taking two big packs with us. We have our own villa with a pool and are also spending the second week at the beach with our own pool, so I am sure we will get through loads. Does anyone have any experience with buying swim nappies in the US? Are they easy to find in places like Walmart or should we take a supply with us to be on the safe side?
