Ah yep, I see what you mean Cailin
Your protective instincts completely. I had a friend years ago, who said that she remembers once a man and a friend driving past her and a friend when they were walking near their home, he wound down window, tried to chat to them...her take on it was, that he was a potential abductor, but as she was so chatty chatty as a kid, it put him off - as she was loud, chatty...
not sure if this helps, but if he is developing into a chatty, confident boy, it will mean he will possibly be a stronger character to deal with life, than a withdrawn kind of child
does that make sense? so him being so strong and confident is a good thing, he has a strong sense of himself already, and will then have a good radar of how to interpret people, and their behaviour, so even himself, he will sense well if someone has good intentions or not.
My 5 yr old has a well developed radar, even since a baby, as I told you about that babysitting incident when he was just 17mths with my mother, and ever since, he won't let her hug him, or brush his hair or put on his jumper - and I never apologise for him. He is his own person, with his own rights, even at such a young age
ahhh sorry long post I do ramble with coffee in my system
