These ovals go inside a Happy Heinys Hemp Stuffin. For boys, place the oval all the way to the front of the Stuffin. For girls, place the oval in the center. Will the insert slip if only placed in half way? No - the small oval insert will stay in place.
 

When you use the small oval insert you will have 7 layers of hemp fleece in the desired wet zone for your child. You can use as many ovals as you need in the pocket for added protection in the wet zone without increasing bulk through out the diaper.
