Hmm at least it stays in the nappy when you use real ones! I have only ever had leaks with disposables. Don't you use liners? I am at the stage where I don't even have to rinse them, the poo goes straight in the loo on the paper, but then TheBubs is just a year old. With no. 2 on the way, I am REALLY not looking forward to going back to the rinsing lark, especially as no1 will still be in nappies unless something amazing happens in the way of potty training. Good luck with starting!
