mummabear bought my little girl two green kids for her bday/xmas, and i am very impressed... they are slighty noisey, LOL but apart from that are easily becoming my fav nappies...
I cant wait till we have some money in the piggy bank caz im gonna stock up on these for sure...
I've heard of many stories of the girls that make these being very accomadating and able to please their customers.
