9 hrs weekly/ babysitter for a preschooler(& 1st grader)

We're a busy family of four. Dad works full time and mom is staying home,but handful with her small business. Our older boy is a sweet gentle 1st grader. Our younger one is a happy little guy full of smiles and laughs We want someone to come play mainly with our 3 years old boy while mama is busy at home or running an errand. Our 6 years old boy is in school full time, so a sitter mostly will not see him, but she may need to also take care of him the days he doesn't have school. Provide snack and lunch for the kid(s) Help with potty training. Willing to do children's laundry and light cleaning on children's room when mom is taking the kid(s) out for classes/appointments. Need total of 9 hrs combined into 2 flexible days (any day is flexible, with morning hours flexible from 8:30am-12:30pm )
