Nanny Needed - Full-time / Part-time

We are looking for an as needed babysitter. Times we are in particular need of are as needed weekend opportunities, Monday during the day and possible evening, and Tue-Friday evenings. At first it would mostly be helping my mom care for our daughter when my husband and I are at work. As time goes on and as the baby boy gets older we would benefit from child care for both of them as needed. Light chores such as help with light vacuuming or laundry would be ideal. If I got home early from work I would love the flexibility to spend time with the kids and have some help with light chores as above. We have two friendly dogs.
