Nicy looking for a babysitter or nanny in Ajax

We are a family of 4. My husband and I are working full time. I am working from home and my husband has to go into office. We have a 5 year old daughter and a 2 year old boy. We are looking for occasional help in the evenings from 4.30 to 6.30 and occasional day help when either of them is mildly sick or day care is off. We are a pet free, smoke free home. Kindness is one non negotiable rule in our home.
