Babysitter Needed for my Children - Full-time / Part-time

We are looking for a date night sitter about once a month for our three children, ages 4, 6, and 8. The goal is to build and establish trust over the next few months to be able to have you watch the children when I give birth in October. Reliability is essential. It would be great to continue occasional date nights a couple months after baby is born, as well. We have 2 friendly dogs in the house.
