BEST pajamas ever! These are easy to get on, but still fit fairly snug. Also, love the built in zipper cover at the top so you don't have to try to snap a cover over it like most PJs on a squirmy kiddo. Besides being super cute on, the material is high quality a little heavier weight than most, but is breathable. My LO is taller and slimmer if that helps gauge where your kiddo might be...
