Weekly Babysitter Needed For 3 Year Old

Hello! My name is Jenn and I am looking for a weekly babysitter for my 3-year-old son- plus an additional 30min window of time also with my 6-year-old daughter when she gets home from school at 4:00 p.m. Henry is obsessed with playing in the sandbox, jumping on the trampoline, driving around the R/C cars, and all things cars/trucks/airplanes! Harper is in second grade and is obsessed with stuffies, Barbies, and joining in on activities that her little brother is doing. My mother watches my son the rest of the week, but I am looking for a babysitter for either Mondays or Fridays to provide her with a little bit of a break. I work from home and will be working in an upstairs office space. I am looking for a babysitter from 10:30am-4:30 p.m. Please let me know if you have any interest in the position. Thank you.
