10

I would say about 13-14. They would be teenagers and would probably know/remember what to do in a situation if need be, compared to the attention span of any child younger. but it would probably change depending on the child.

I'd say 12.

13 or 14.

11-12 thats when i started very simple

11-12 is a good age where they should know the obvious.

That's the age my parents left me and my little brother inside alone .

13 ish

Also depends if its a girl or a guy

I guess it really depends on the situation.

You can't really put a definitive age on it. It depends on a lot of things which aren't entirely controlled just by age, such as their physical strengths and weaknesses (Could they escape or fight off the attacker?), or how mature they are mentally.

I'd say 12 and up but it really depends on the child, everyone's different.

13-14

If I'm running inside the store, and I can see them from the window. 13- 14 otherwise I wouldn't leave my child inside the car.

Probably about 9

Depends how they were trained. "Don't open the door for anyone but me"

Some people may not agree with me but,
If their just babies, and I have to run into the corner store to get just 1 thing, I'd park the car infront of the store / Gas station, lock it and keep it on, with the AC (if its summer) with the window down. Thats just to get 1 thing, because it's faster, and less hassle. If I need to do grocery shopping or something that requires more then 2 minutes then i'd definitly bring him/her in.

and your plan to get back in your car?

Get a remote car locker thinggy.. lol.. and have a seperate keychain with it.

I honestly don't think age matters. What matters is how long you're going to be whenever you are going.But that's just my opinion.
