My dd is 4 and full of beans, which is lovely but I realised today that she has no sense of 'stranger danger'. She will quite happily talk to anyone. We went to the cathedral green so she could look for conkers, and while I was getting ds out of his pram so I could put him on a blanket on the floor she had found a nearby young couple with a girl of about 9 with them and managed to persuade them to help her look. She was never out of my sight, but I didn't know these people. They were very good about it and really made a show of helping her for 5 or ten minutes. When they left she walked over to a woman who was a few feet behind us, who was playing with her 8 month old, and started telling her all about her baby brother, and playing with the baby. Again, the mother was very friendly, but I wonder to what extent people thing 'fgs leave me alone, where is your mother??' I don't think my dd would actually go off with anyone and she never goes where I can't see her, but how do I instill a sense of vigilance in her without making her scared iyswim? She is a bit of a motor mouth (her favourite thing to do atm is compliment anyone she sees out and about 'ooo I like your handbag, what a pretty dress' etc) and I know she is just being friendly, but where do you draw the line? The more I think about this the more I realise I don't have an answer and I just want to keep her safe
