We have appointed on the advice of our pediatrician trial basis a woolen nappy pants and tried to "keep the kidneys warm" over the winter! :) We have now stayed with the woolen overpants have per size ca 3Stück so we can rotate when a time is in the wash, they are allowed by the (cold) wash cycle do not tumble dry, Contrary to many users we use it in combination with Pampers etc. and not with cloth diapers. The days pants must be a little more generous cut to tuck the diaper package, the freedom of movement but is impaired in any way - quite the contrary, benefited the little sparrow of comfortable clothing. And: Our daughter was not even throughout the winter cold -the kidneys were warm !;)
