Children older than that can be left for a range of 2 - 24 depending on age.   Answer   I think the previous response and question need clarification. I can't imagine my child being 14 years old, and not allowing her to stay home alone. Most baby sitters I know start baby sitting at 12 or 13.   Answer   For children with normal mental capabilities: Ages 7 and under cannot be left alone for any period of time. Children ages 8 through 9 can be left in their home alone for up to 2 hours. Children 10 through 13 can be left alone for up to 12 hours. Children 14 to 17 can be left at home up to 24 hours with adequate adult back-up supervision (an adult willing to take legal responsibility preferably within 5 miles).
