i have not done that, and i don't think i would until my child is 15 or so and with a sib or cousin. When she turns 18 she can have a tine bit more freedom, i guess you could say i am overprotective, but there are so many things happening in the world today especially with our children, and it can happen anywhere. To sign herself out 15 but i do believe it really depends on the maturity of the child also. Some are more mature then others.
