Experienced Babysitter For 2

I am looking for a babysitter who would be available for days that my husband and I need additional help because of conflicts in our work schedules and the occasional evening date nights/ work events. I have a 2-month-old little boy, A, who just started smiling and cooing. He really enjoys time with his big sister, fresh-air, and cuddles. My 2 1/2-year-old, M, enjoys playing outside, riding her bike and doing art projects. Staying active and engaged is important to us. We're looking for someone who will spend quality time with our kiddos. Someone who has patience and is interested in engaging with children.
