The going rate for an adult babysitter in my neighborhood is $25 an hour if you have two or three kids. Though there are online caregiver calculators to do the math for mom, some parents prefer to do some research at the playground or inquire among friends to figure out a competitive rate. If they are attempting to steal someone else's sitter, the stakes are higher. Other factors like driving children, doing light housework or tending to tots overnight may up the ante as well. How much do you shell out (per hour) for a babysitter? And, how often do you hire help?
