I NEVER write reviews but I had to for these! They are amazing! They are the softest thing and super stretchy. I love that there is no zip bunching up in my little guys face when he is not laying completely flat, like they do! I love the amount of stretch they have, I’m not worried that the legs will ever squish his toes when he straightens his legs, even when he gets to almost growing out of it. The fit is amazing right away, it looks so comfy I wish I had one! My baby boy is 3 months old, if I’d have known about these sooner these would be all I would have used when he was newborn! Would make such a good shower gift!
