Babysitter Needed for my Children - Now Hiring

I'm looking for a wonderful nanny to help us during the week. We have a full time nanny and she needs help in the afternoon with the 1-year-old when she goes to pick up the 3 and 5-year-olds from school and take them to their afterschool activities. It would be to care for the 1-year-old, take him to the park, give him a snack, meet the older boys in the park and feed him dinner. Occasionally it might be to collect the older boys from school while our nanny stays with the baby.
