Measuring Your Baby

To measure your baby's thighs

Measure where the elastic of a diaper would normally be - around the meatiest part of the baby's thigh.

To measure your baby's rise

Measure from mid-back at the waistline to slightly below his belly where his/her diaper normally would come up to.

*Please note: These measurements take into consideration only one insert in the Fuzzi Bunz at a time. Always try your new Fuzzi Bunz on your baby with an insert for size before washing / using.

If the size chart is still baffling you...

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

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

Disclaimer: Our Size Chart has recently been updated to reflect more up to date size data. Fuzzi Bunz diapers have NOT changed their sizes - only the size chart.
