One item that I'm consistently told people have trouble finding is gowns. This seems to be to be a huge oversight and I wonder why that may be. For us, as with many people, they were a huge help!
Gowns are perfect for the newborn stage, when diapers seem to be changed every five minutes. The elastic opening at the bottom allows you to quickly push up the gown and change a diaper. No messing with snaps or zippers. The envelope neckline allows you to pull the gown down, over your little one's shoulders, in case of a blow out. No one wants to pull a poopy article over the head!
