A: A fourth cousin is someone in a family who shares the same great-great-great-grandparents. First cousins share the same grandparents and second cousins have the same great-grandparents. Ordinal numbers of cousins are in the same generation as each other.
8 to 10 years-Should not be left alone for more than 1Â½ hours and only during daylight and early evening hours. 11 to 12 years-May be left alone for up to 3 hours but not late at night or in circumstances requiring inappropriate responsibility. 13 to 15 years-May be left unsupervised, but not overnight.
(See the chart below). The National SAFEKIDS Campaign recommends that no child under the age of 12 be left at home alone. However, consider a child's age and maturity level. For example, if a child is extremely impulsive, it might be best to wait until he or she is older than 12. There appear to be very few states with specific regulations about the age of a child left at home alone.
