DS (just 2) can wee through a large Itti Bitti D'Lish nappy in just an hour - so much so that it wets through his trousers and I have to change both nappy and trousers. I don't know whether the nappy has gone wrong or that he's just bigger now so he can wee a lot more and it's just too much for the nappy. I find myself just putting him in disposables as I'm doing too much washing, which I hate doing as it's a waste of money. Help!
