Contrary to popular belief, there is no set law in Colorado that gives a specific age when it is legal to leave a child home alone at home. Many people go by the Colorado Child Labor Law and consider 12 the minimum acceptable age. However, there are many other factors to consider, including the child's maturity level and whether he will be in charge of anyone else, such as younger siblings or when babysitting.
However, because there is no definitive age and the circumstances and child's maturity level factor in so greatly, parents must be very careful. Leaving a child home alone who is not ready for the responsibility could lead to someone getting hurt, damage to property or charges of child neglect.
