Bought this for my son to wear when we brought his baby brother home from the hospital, and it was a hit with the whole family. The cotton is breathable enough that he didn't get sweaty crawling around all day.

The organic cotton is so incredibly soft on my baby’s skin, and the “lil bro” print made the perfect announcement photo without any irritation.

We used it for our son's arrival announcement and the little graphic is so perfectly sized you can't miss it in the photo. The organic cotton is breathable and the fit was true to size, so I've already ordered more in bigger sizes for him to grow into.
