Babysitter

Our nanny had a sudden medical emergency and will be out for at least 1 or 2 weeks. Looking for temporary help. Our son is 18mo old and typically stays at home with his mother. My wife is going through chemotherapy and so we're looking for help watching him, especially in weeks where she receives treatment (which is every two weeks). We also have a daughter, who is 4, and goes to day care M-Th. You'd be helping alongside my wife. We're in Madison NJ.
