Nanny Needed

We are looking for someone to watch our 3-month-old baby girl on Mondays and Fridays. I go back to work from maternity leave in November. We have two other older kids. Both boys, ages 4 1/2 and 3 years old. They both will be in school during the day. We would need help with getting the oldest off the bus at 2:30 at the end of our street. Hours would be 7:30/8 oclock start, with the end times varying around 3-5 oclock. We would prefer a nanny who is comfortable with pets. We have an older dog that is very energetic when you first walk in, but give her 10 minutes and then she will be laying in her bed all day. We would prefer someone who is CPR certified.
