The Diaper Valet from MoMamas is a really useful product, I am about to have number 2 and am a little less enthusiastic about carrying the entire nappy bag with me where ever I go compared to the first time round.
The wipes case fits in a slot and wipes are accessible without having to take the case out, and there is more than enough room to hold 5-6 nappies. There is also enough room to carry an extra change of clothes for emergencies. The bag is surprisingly small – about the width and height of a nappy case – and it easily fits in any bag.
It comes with a thin changing mat and you have the option of adding a handle to make a sort of purse out of it. There are a number of fabrics to choose from to create your Diaper Valet and prices are US$23 – US$30 plus shipping to Australia.
