Part Time Sitter For 20 Month Old Boy!

I'm a stay at home mom looking for a part time sitter for our 20-month-old son, 3 days a week, from 9am- 12 p.m. (before his nap). During this time I will either be doing things outside of the home or cleaning/projects around the house. The ideal candidate will keep him busy by playing with toys or simple crafts in the playroom, as well as some occasional food/ drink prep. On occasion, my husband could be working from home in his office but spends most of his morning away. Additionally, we have a 6-year-old son who attends school during this time (unless a snow day or school holiday/ day off). We have two cats as well who keep to themselves. Flexible on what days of the week you come, but preferably a set schedule.
