Now I’m familiar with inverted zippers on some swaddles I used with my daughter 3 years ago and loved them for night time diaper changes. However, I’m just now discovering they have inverted zippers on jammies and sleep n plays?!? I’m super excited cause what baby likes to be unzipped for diaper changes? Now you can just zip up the bottom to belly button and baby stays cozy (except for the breeze down there and cold wipe). Makes me think what else is new out there that I could be missing (since I’m using mostly hand me downs).
