In a nutshell:

XS FuzziBunz® are generally for preemies. If you want a very snug fit for a small newborn, these will work, but will be grown out of quickly. We do not stock these normally, but they can be special ordered.
Small FuzziBunz® best for most newborns. Usually fit through to about 7 months before mediums are needed.
Medium FuzziBunz® will fit most babies from 4+ months. Your baby will probably stay in size medium the longest. Many babies can wear mediums through to potty training without needing to go to large.
Large FuzziBunz® generally don't fit until at least one year of age or unless your baby is of 12 month old weight range or tall for their age.
Petite can be special ordered on request. Slim babies usually fit just fine in size medium without needing petite sizing.

XL is for potty training toddlers. Can be special ordered on request.

**The above guidelines assume you are only using one insert in your diaper. Please try your new FuzziBunz® on your baby with an insert before you use or wash them to ensure proper fit.
