The open bottom gown + hat set is a wardrobe staple for newborns who require constant diaper changes (aka all of them). with an opening at the bottom (thank you, cinched elastic band), baby’s top half stays warm during the diaper switcheroo: pull the gown up, put on a freshy, and you’re done. other amazing features: organic cotton, built-in mitten cuffs, magnets at the top for easy over-the-head dressing.
