I regularly receive inquiries from parents about the age at which children can be left alone. There have been recent publicized cases about children left alone. In Maryland, there is no simple answer. It is prohibited to leave a child under 8 alone at home, in a car, etc, but it may also be deemed neglect depending on the circumstances even if a child is 8 or older. A number of considerations are relevant, including the maturity of the child, any physical or mental disabilities, how long and where the child has been left. Keep in mind that even if it doesn't rise to the level of criminal charges or a neglect case, it may still be relevant in a custody issue.
