The age range in our sizing should be used as a guideline. Babies come in all shapes and sizes and there is no universal sizing to fit all. But luckily, knits are very stretchy!  You will find that for most styles your pieces will last longer than the size range indicated.

Our sizing is based on a child in the 50th Percentile. This is a great gauge on wether or not you should size up, or size down:

Also, we are big fans of sizing up (i.e. if your baby is a big 4 month old, get the 6-12 month size) 
If you are unsure of what size to get, check out the size charts listed with each product or open a support ticket, we are always happy to chat with you.

You can also ask questions for specific pieces right on the website! Just click “Ask a Question” on the product page and we will answer you there.
