Babysitter Needed For 3 Children In Dallas. Two Big Girls & A Teen-ager.

We are looking for a great babysitter for 3 children in Dallas. We would prefer a babysitter who has their own car, just for emergency purposes. My girls are very well mannered & love meeting new people. They are almost 9, 6, and 4 years old. They are very helpful in our home & know how we operate the ins and outs of our day to day routines and expectations. We need babysitters for overnight sometimes but mostly for random weekends if we are unable to get a sitter. I would love to have a consistent and steady nanny who is essentially known in our family.
