Sitter Part-time For 2 Children

Looking for a reliable long-term sitter for Monday and Thursday late afternoon early evenings. This would be a consistent weekly schedule, but we are also looking for occasional additional hours possibly on a weekend day, but would let you know in plenty of advance time. Looking for someone with experience caring for multiple children. We have a 4-year-old and a 9-month-old. Plus if you have experience with autism and special needs as our 4-year-old is autistic. Mondays and Thursdays I work from home so you would need to be comfortable providing care with a parent in the home. Occasional additional times as listed above parent would not be in the home. Duties would include just caring for the children, typical things like feeding, diaper changes and keeping them safe and playing with them while I'm working.
