These amazing Rompers are “Grow With Me” style! To make the smallest size you pull the hidden drawstrings on the inside of the Romper to make it smaller (these are sewn in so no need to worry about losing them in the wash!). You can also fold up the cuffs at the bottom of the Romper 1-2x to make it smaller, AND adjust the snaps at the top to the smallest size. To make bigger you can undo any of these steps to slowly help it “Grow” with them.
