How much does a nanny cost in Chicago? It's for a single infant ( 3 month's old). 40/hour week and long-term. Family lives in LP. Looking for a nanny with 5+ years infant experience, certified, vaccinated, English speaking, and willing to have taxes withheld. Only expectation is housekeeping centered around child. We were thinking $16 ( net) with raises and bonuses in the future. What do you pay or charge?
