Good luck Charlie: Baby come back

PJ takes Charlie to the park and accidentally switch the strollers with a girl named Emma, and brings home the wrong baby. Teddy, PJ, and Gabe search everywhere and they come to the point where they have to tell Amy and Bob.  Amy and Bob go on a date to a Mexican Restaurant to get their minds off of Charlie, but when Emma shows up at the restaurant that Bob and Amy are at, the Duncan kids sneak in to switch the babies.
