Baby gowns often refer to loose-fitting baby nightgowns or baby sleeper gowns. The newborn baby requires many changes throughout the night. A gown opens at the bottom making this task much easier. The problem with them is they tend to scoot up during the night. We would buy baby a gown that closes with a drawstring or by knotting the bottom together.
Baby gowns can also refer to the Christening gowns used in a baptismal ceremony.
