I am babysitting right now.  How long should I be able to leave a nine year old home by themself?
<|assistant|>
Nine years old is too young to be left home alone for an extended period of time. Most experts recommend no more than two hours at a time, and suggest adult supervision is needed for any length of time. Additionally, depending on the individual, nine year olds may need more structure and guidance than usual while you are gone.  It is suggested to stay nearby so that you can quickly assist if needed.
