Set includes three gowns | Made with 100% cotton | Soft, gentle and comfortable on baby's skin | Optimal for everyday use | Based on customer feedback, our size preemie is optimal for preemies and newborns from 6 to 9 pounds. Customers also say our 0-6 month gowns run on the larger side, which is so they last until your little one is 6 months old. Note our gowns are made with 100% cotton, so some shrinking should be expected.
