Size Chart - Zippy – Little Sleepies
FREE SHIPPING ON ALL US ORDERS!

Babies grow SO fast! That's why we designed our sleepwear to be extra flexible in sizing. All of our styles have extra length (easily roll up any extra), foldable foot cuffs (traditional footies are so limiting) and super stretch for longer wear! They are designed to fit snug in accordance with all CPSC guidelines (as they are not treated with any nasty chemicals!). Read more about the breathability and benefits of our fabric here.

The below guides are based on feedback from hundreds of customers.

We recommend sticking to true size/age for the Zippy - there is room to grow and no need to size up.
