Babysitter Needed for my Children - Now Hiring

Pretty much just the 2 younger kids that need to be watched after. Our 2 oldest are really self sufficient. Not too many specifics for care wise they all have their own way of hanging out and doing things. They watch TV or their tablets or play with toys. They like arts and crafts and playing hide and seek. We have a small back yard with a pool and these kids will stay there for hours if we let them.
