so cozy and soft
I ended up buying both sizes of this for our newborn. I initially bought the 3-6 month size thinking it would fit younger as we are tall and have tall babies. I could tell before baby was born that it was way too big. The 0-3 month size fit our 8lb 6oz baby boy loosely right after birth and he was in it until just past 2 months. So I would say these are fairly true to size. It does pill a lot so I've had to remove lots of fuzz balls to keep it looking nice. But it's so soft and cozy. We used it every single day with just a onesie underneath. (And still do with the 3-6 month size) The larger size could have used 5 buttons instead of 4 since it's so much longer but it's still very functional. I recommend using a bib once baby starts to drool a lot as I learned the hard way it can felt easily when soaked with drool. I also recommend buying the Disana gall soap in case of poop blowouts. I Love this suit. Highly recommended!
