With the arrival of the new baby, Andrew feelis like a burden to the Emerson family and moves into the local senior citizens home. Joey volunteers to be the baby's guardian in Roc and Eleanor's will, and to prove that he isn't irresponsible, Joey cares for the baby in his apartment while Roc and Eleanor have a romantic evening together.
When Roc and Eleanor bring their new baby home from the hospital, Eleanor's mother, Margaret, immediately accuses Roc of raising the child incorrectly.

Eleanor instructs Sheila on how to defend her dignity against sexist remarks made by a rude boy at school. Meanwhile, Andrew asks Joey to take his senior citizens group to the horse racing track. When Joey addresses the seniors about betting on horses, they criticize him for gambling instead of working at a job.
When Roc finally realizes the importance of prenatal care for the health of their baby, he obsessively pampers Eleanor with food, exercise and music.

Joey tries to win back a large wager that he lost to Al in the past but is unsuccessful.
When Roc's crazy neighbor George is hired by the Sanitation Department, Roc is assigned to teach the annoying man how to be a garbage collector.

After being sentenced to prison for the attempted murder of a local drug dealer, Calvin asks Roc to take care of his 11 year old daughte, Sheila. Roc agrees to assume custody of Sheila as a favor to Calvin, whom he admires for his courage and sacrifice in wounding a powerful drug dealer. Roc learns that Sheila is angry with her father for leaving her homeless. Roc explains to Sheila that Calvin believes he was protecting her and the other neighborhood children by committing the crime.
