Rach, The pool man says that we can use the disposables or washables, 'as long as all the solids are kept within the nappy'. And I did google bright bots, there is noone near me that sells them. The closest people from the list at bright bots don't sell them anymore!
Lesty, I spoke to the swim school man yesterday, and he said that some people do wash and reuse the lil swimmer nappies sometimes, but that would be my choice...
Saram, I wish I had looked at the Belly marketplace first. I could have ordered one from you!
Ray, I saw a pair of those wetsuit type nappies, but I couldn't figure out if they had adjustable waists or not.

I called one of the other pools in Sunbury, and they sell the washable ones. I will look at them tomorrow, and if I don't like them, then I guess I will have to get a pack of lil swimmers, and buy a pair from the belly market! That is, unless I can miraculously potty train Steph in one day.....
