Babysitter Needed

Looking for a nanny to help my wife with our 17-month-old son and 6-year-old daughter. The job starts at 1 p.m. and my wife will pick up our 6-year-old daughter from school. We are looking for someone to help with structured activities and general child care. My wife is entering her 2nd trimester of pregnancy and will need help covering the kids so she can rest. In the evenings she will need help getting the kids fed and bathed/showered for bedtime by 7:30 p.m. We want someone who will help create an environment of structured and respectful boundaries for the kids to follow.
