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

We are looking for a great babysitter to watch 2 children in Wenatchee for an afternoon. We have a 10-month-old baby and 7-year-old. We'll be on vacation / business staying in a hotel in Wenachee for a conference. Baby is the sweetest baby. She is almost always happy and very good tempered. 7-year-old boy has some energy and would enjoy a visit to a nearby park but would also be pretty chill if he's allowed to play on his electronics. We'd appreciate a local sitter with good insight into local spots that are good for kids.
