Baby Sinclair enters the "terrible twos" and his behavior becomes horrendous. Desperate times require desperate measures, and the Sinclairs enlist the aid of "The Babysitter" to exorcise Baby's demons. When neither the exorcist nor doctors can cure the baby, Robbie hatches a plan for the family to fool Baby into believing he's three.
