In Just a Baby, Brenda's sister, Debra, arrives for a visit with her new baby, Jamal. Little Bill accidentally frightens the baby when he sings too loudly, and Big Bill explains how babies like soft music like lullabies. Aunt Debra gives Bill the job of telling her when Jamal has woken from a nap, but when the baby spits up, Little Bill fears "he broke the baby." Bobby teaches Little Bill that babies sometimes make messes and shows him how to hold Jamal properly.
Baby Jamal is April, Bobby and Little Bill's maternal baby cousin and the son of Deborah (Brenda's sister) and Gary.
