My hospital used Pampers Swaddlers size N in the Newborn Intensive Care Unit the first 2 weeks of my son's life and then 6 packages were sent home with me to use. The nurses bent the front edge of the diaper under while his belly button healed and it stayed folded quite nicely. He was born at 4 and a half pounds and was growing rapidly but the tabs held it closed well and he remained dry despite his amazing ability to fill diapers!
