The more things change, the more the Seavers stay the same!
And they do change, as the fourth season of the beloved family favorite sees Mike (Kirk Cameron) starting college, Carol (Tracey Gold) starting to get cynical, Ben (Jeremy Miller) starting to date and Maggie (Joanna Kerns) about to give birth!
While Jason (Alan Thicke) does his best to keep the family grounded, he finds his clan starting to chafe at their old roles—like when he tries to actually ground the `grown-up' Mike. As father and son reconcile their changing roles, Maggie confronts her fears about labor and Ben has to deal with his new baby sister, Christine, stealing his birthday and his place in the family.
But Big Brother Ben has more than enough Seaver sense to rise to his new role while the clan confronts new challenges, along with some special co-stars such as Jane Powell, Matthew Perry, Dick Van Patten, Cuba Gooding Jr., and Brad Pitt!
