Kids grow SO fast! That's why we designed all our styles to be extra flexible in sizing. Our pajamas have extra length (easily roll up any extra), foldable foot cuffs (traditional footies are so limiting) on our zippies, and super stretch for longer wear! All of our PJs are designed to fit snug in accordance with all CPSC guidelines (as they are not treated with any nasty chemicals!) and Play by Little Sleepies, our new line of daywear, is made with the same super soft fabric you've come to love.

The below guides are based on feedback from thousands of customers. Check out our reviews for customer testimonials, photos, and to see just how much everyone loves Little Sleepies!
