Baby Brother (1927)

Joe Cobb is a wealthy child who longs for a baby brother. His nursemaid takes him to the other side where he meets some kids his age (the rest of Our Gang) where Joe offers three dollars for a baby. Farina finds a fellow African-American neighbor woman who lets him mind her infant which he then paints white and sells to Joe. The rest of the gang has set an assembly-line system that washes, dries, rocks, and feeds male and female babies.
