Measuring Your Baby
To measure your baby's thighs: Measure where the elastic of a diaper would normally be - around the thickest part of the baby's thigh.
*Please note: These measurements take into consideration only one insert in the FuzziBunz® at a time. Always try your new FuzziBunz® 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 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, are in the weight range, or are 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.
Will I need to buy all these different sizes? Definitely not! We have found that most babies only ever need Smalls & Mediums, as they tend to potty train right out of the Mediums and don't end up needing anything larger.
Why are there so many different sizes? Fuzzi Bunz has made a special effort to recognize that all children are shaped differently, and so they have developed several specialty diaper sizes in order to accommodate all shapes and sizes as much as possible. Most children will only ever need 2-3 sizes before they are potty trained, however.
