Happy Heinys understood that some One Size diapers will never fit a newborn and that is why we have designed our Mini One Size. What is best about the Mini One Size is that it is not just for the newborn weeks. You can use this diaper from 4-15 lbs which for some babies can be 6 months-1 yr. This will help to get you through those early tricky weeks when most babies leak through all one size diapers.
The Mini One Size diaper comes with 2 inserts just like the regular One Size diapers only they are extra small and small.
