I have two daughters, S. who is 10 and T, who is 6. S, stays with her dad every other week during the summer, so care for both kiddos will not always be necessary. They are generally very easy to care for. We just need someone there for a few hours each day during the summer to help structure their activities and play with them while my husband works at home and I work out of the home.
We have a lot of pets, so someone who is comfortable with that is necessary. We have six cats and two dogs that move freely throughout the house. We also have three snakes which you will not have to interact with at all (or even see if you don't want to), but should know are in the house.
