Babysitter Needed for my Children

We are looking for a great sitter who is comfortable with both toddlers and newborns. My toddler is in daycare during the week and I expect my weekends to be busy. I am looking for a postpartum babysitter for the weekends who can handle one kid while I focus on the other kid. We would prefer a babysitter who does not smoke, who is comfortable with dogs and who is CPR certified.
