Here is some information on my experience with babysitting/nannying:
When I was growing up, I babysat my sister until she was old enough to be home alone. For the past 4 years, I've been a nanny for my neighbor over the summer while the parents worked during the day. I also have been occasionally babysitting my nephews since the oldest (who will be 6) was born, and have watched all 3 at the same time, so I don't have trouble watching multiple kids of any ages.
I enjoy cooking and I don't mind cleaning, so if chores need to be done while kids are napping or sleeping, I'd be willing to do them! I love playing board games, card games, video games, and made up games, as well as crafts. I love kids of all ages!
