latchkey child(redirected from a latch key child)
A child who is home alone after school or in general because their parents or guardians are at work. I know it makes me sound horrible, but I just don't want Tommy hanging out with those latchkey children from down the road. Being a latchkey child was tough at times, but it taught me the value of self-reliance at an earlier age than most.
