Occasional Daytime Sitter For 3 Year Old Girl, Other Kids, Date Nights A Plus

Hi! Looking for a casual occasional daytime sitter for mainly my 3. 5 year but sometimes could include her plus another one of my boys depending if its after school. I sometimes have appointments during the days or when I need volunteer at the school or take my other kids to sports or dr appointments so it would just be for a couple hours here and there and not more than a day or two a week. I am thinking a college student who has a flexible schedule would be perfect to call on when needed. If you're around for date nights occasionally that's also a plus!
