Battling for Baby

A young couple are going to have a baby just a few months after they are married. They hadn't planned it so soon but go ahead. But then there's the grandmothers. They've hated each other for years. It seems one stole the boyfriend of the other, married him, then divorced him. So there's this rivalry to take care of the baby. The dialogue is funny, the situations are quite real and well played by all the cast, especially the veterans, Suzanne Pleshette and Debbie Reynolds.
