Babysitter Needed for my Children

We're looking for a caring and reliable part-time nanny to help with our 3-year-old daughter and 20-month-old son on Tuesdays and Thursdays. I'll be home at times with our 5-month-old but will also be coming and going for appointments and errands. Responsibilities would include playing with the kids, keeping them active and engaged, preparing simple snacks and lunch, and putting my son down for his nap.
