No, don't go back to nappies. My boy got off to a really good start then decided to exercise his control and got a bit resistant but has since calmed down and is slowly getting better and better. Once he got used to pants he much prefered them, far nicer than a sweaty nappy in the hot weather. You might be thinking in a few days that it just isn't working out and then you will have a bit of a break through. It's tough, wee and poo is all we have talked about for weeks in this house.
