DD is coming to the age now where her friends have started having a bit of independence. One of her friends on the street who is the same age plays out by himself and has been asking if dd can play with him. She hasn't yet (he's only asked twice and we were going out) but I would only really feel comfortable with it if I could see her from the window.
Also she is getting quite a few party invites where parents don't all stay. The thought of leaving her at a party terrifies me tbh. Most have it at the local playbarn and the gate to outside is just left swinging open most of the time.
DD is my eldest so to those of you with older kids - what age did you let them have a little freedom and trust them to be sensible and not wander off?
