Here is some additional information for you to use in trying to choose the best size for your baby:

• XS FuzziBunz® are for either preemie or very small babies
  - they will fit newborns very well, however, not for a very long time.

• Small FuzziBunz® will fit babies that are newborn (although they may be a tad big
  at first) through about 6 or 8 months of age when they are ready for the mediums.

• Medium FuzziBunz® will fit babies with either small or large thighs. Medium is our
  most popular size because babies stay in this size the longest!
  They will fit babies from about 4 months old (depending on their growth rate
  and size build) up to potty training stages.

• Large FuzziBunz® will generally not start fitting your baby until at the very least,
  12 months old or are in the weight range or very tall.

• Petite, Toddler and XL are specialty sizes. Mediums have been found from our
  size testing to fit better and for longer periods than the Petite size diaper for skinny
  toddlers. XL can be used for older potty training children or other circumstances where
  larger diaper is needed.
