Sizing Chart for Roomy Convertible Sleepers

Designed with added length and width for babies who need a little extra room for comfort or simply need a little more to grow.  

Our signature fit is roomy where it matters most—so your little one stays comfortable longer and parents get more use of their baby’s sleepers.

Between Sizes?

If your little one is in the 70th percentile or above for height or weight, we recommend choosing their current age range.

If your baby is between sizes—or you prefer a little extra room to grow—we recommend sizing up.
