Babysitter For 2 Little Kids!

We are currently looking for someone to babysit our two children a couple times a week, (Wed &/or Thurs) for a couple of hours, (2 to 4 hours). Hours and days are flexible. I plan to be home during those periods but want to use the time for rest or get tasks/projects done. My son (3. 5 yrs old) and my daughter (15 mos old) enjoy playing outside, going on walks, exploring the yard, doing crafts, reading a lot of books, playing with toys, and imaginative play. The babysitter is not expected to do any cleaning, meal prep or any other chores. My daughter would need diaper changes and my son is potty trained. I will have their food and drinks ready. We have one dog. He will not be needing any care.
