FuzziBunz® Mother of Eden inserts are the same inserts that come with the FuzziBunz® Perfect Size diaper. These are micro terry inserts made of four layers of super soft micro fiber terry cloth. These inserts are super absorbent and super trim at the same time. Inserts can be used if extra absorbency is needed. Most babies only need one insert during the day, but some require two at night to prevent leaks.
