Nanny Needed For My Children - Full-time / Part-time

My son is in 7th grade. He will ride the bus to and from school. I need help getting him to and from karate after school, ensuring he has a snack after school (he has an eating disorder -ARFID-, so he sometimes needs to be reminded to eat), and some light cleaning or occasional meal prep. I also have 2 adorable dogs that would love an occasional belly rub and a cat who sometimes hangs out with us. I have been trying to do it all while working full time for a year and am worn out!
