Massachusetts does not set a specific age at which a child can be left home alone. In Massachusetts, such issues are decided on a case-by-case basis. For information on abandonment and neglect, see MGL c.119 s.his definition is not dependent upon location (i.e., neglect can occur while the child is in an out-of-home or in-home setting.). Other states have provided some helpful information for parents on the topic, however. See, for example, Florida's When to Leave Your Kids Alone.
Children above that age can be left alone for a couple of hours and we look at the maturity level of the children up to 12 years of age. There is no law in KY that addresses this issue. Don't leave young kids alone in Kentucky. A child should not be left home alone in Kentucky until they are 11 years of age. There is no law per se, but I work in the child welfare arena and if your child is younger than this and being left alone child protective services will take a report and investigate a child left alone younger than 11.
