Just been to mom's and tots, we had a visit from the police telling us to be extra careful and to try and teach the little ones a bit of stranger danger as there have been two reported instances of attempted abduction in the area recently!!!! How do you do that without upsetting the kids? They range from 0-4 i suppose the real issue is with the ones who are mobile but how do iget a three year old to understand?
We had a camera stolen while I'm on holiday. I explained the snatching risk to my 3yo like that -- "Do you remember that camera we had? Someone stole it and we never saw it again, I don't want anybody to steal you, so don't go where I can't see you".
I know it's blunt, maybe you can be more subtle with some children; mine need the message plain & simple to understand the point. I didn't try to teach him (at 3) not to talk to strangers, that one was too tricky.
mummyhill... I used to look after a little girl and took a similar approach to Xzebra.
I used to tell her that she either had to be in the buggy, or stay with me in case someone stole her, or in case she got lost.
It worked, and if she started wandering off i would just say "tabitha, stay with me" and she would say "yes, don't want to get stolen... daddy be cross!"
