This waterproof underpants is admittedly somewhat more expensive - but absolutely worth the money! You should of course be a substitute for diapers - it is not designed. Your purpose is to sensitize the child for urinating by noted when it starts - namely when the moisture feeling announces in his underpants, which in proper diapers is never the case. And then to learn and adhere to the toilet. For parents, the big advantage is that the clothing worn over not completely soaked. The pants are comfortable to the touch (breathable) and top handles, and the designs offered are magical. After a long gestation period and frequent washing as new! A great idea to facilitate the drying time becoming, for parents and children - and with style :-)
