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

Have had a wonderful sitter who found a job in her field starting mid-summer. As a result, need to find someone who can watch the kids during the day while I work from home. The "big kids" 3. 5 and 5. 5 go to preschool for a portion of the day - generally 9-3. Most of the day will be watching our 1. 5 yr old. He loves bears, playing ball, books and food. He goes down for a nap generally 1-2:30. Would need help getting him breakfast (scrambled eggs/fruit) and lunch (heat up meatballs etc.). Hope to hear from you!
