RhiChiChi: Yeah she needs to be in the larger size, she weighs about 14kg's - so not big for a almost 3yr old - but the smaller size is too tight around her tummy and legs and they rub so I had to go the next size up. I've also tried nappy pants to help with the rubbing issue but we still has the same leakage issue in them as well.

Maybe it is just something we need to work with and who knows it might kick start her into TTing if she keeps wetting herself...
