--> ''Full House: Our Very First Show"

So the [[DotingParent Loving Mom or Loving Father]] has to take off for their job or some other very important mission. Time for the other parent, who is [[MarriedToTheJob rarely at home]] to watch the kids. If they are a single parent, maybe it is time to hire the [[JerkWithAHeartOfGold unlikely godfather or uncle]] or have your [[JustFriends friendly coworker/neighbor/sibling/best friend]] come over to babysit just for the night.

If there is a child under the age of three years old, this trope will certainly come into play at some point. Especially if you have a male caregiver taking over. Often involves somebody who doesn't know how to or is inexperienced at changing diapers for comedy. Most often seen in family movies or television shows with infants in the family.

A TinkleInTheEye will often come into play if the child is a boy.
