Hey Mama!
We have a sizing chart that can be located at the bottom of our page.
But when In Doubt - Size Up.
Our designers have done their best to make our products run / fit as true-to-size as possible. With this said, we absolutely realize little ones come in all shapes and sizes, as well as grow at different rates.
If you're ever in doubt as to a size, we always recommend sizing up - kids don't ever seem to get smaller!
Our Cliqq Mamas also leave the sweetest reviews and you can peruse these to read about some of their sizing experiences.
