Don't chat with friends all night or occupy the phone so that the parents cannot reach you. Use the phone only for emergencies. Don't ever invite friends, girlfriends, or boyfriends. Parents do not like this, and you are not focusing on the job you are being paid to do. Unless the parents approve, do not feed the kids hot dogs, peanut butter, or hard candies to avoid choking or allergic reactions. Unless you have experience, do not babysit too many kids at the same time. Children can quickly overwhelm an inexperienced babysitter, and accidents may occur. Don't ever leave the kids alone. Check on them even after they have gone to bed to make sure they are fine. A good plan is to check on the kids shortly before the parents arrive home to ensure that the children are fine.
