Babysitter Needed for my Children - Full-time / Part-time

We are looking for help 5 days/week, but only part of the day to help get our 2 elementary age kids on the bus in the morning and off in the afternoon. Would also need help taking out our dog in the afternoon for a walk. Morning hours are about 7-9 a.m. and afternoon hours are about 2-4:30 p.m. Willing to work with someone who can only do the AM or only PM, as there is a childcare option at their school too (I don't want to use it for both am and pm though). May have days were all 3 of our kids need care if our youngest (3 y/o) does not attend her daycare. Reach out with any questions, thanks!
