I think it's a lot to do with his personality.

Jacob runs like a mad thing and throws himself into anything! He is always in such a hurry to do everything! If something isn't done quickly, then it's not worth doing in his opinion and he gets agro! LOL He climbs and does all of that kind of thing too - he has no fear! But I have noticed that in social situations where there are adults around that he doesn't know, he tends to be a bit on the shy side and wants to stay very close to me initially. It may take him anywhere up to say 20 minutes of being VERY cautious, but then after that, you'd generally never know that he hadn't met the person before as he starts taking them books etc! LOL He's generally ok with other children - he really enjoys watching them and playing......more so than what he once did because he generally plays independently a lot of the time - he likes to do his own thing (even when we try to play with him he will take off with his toys so he can do his own thing with them!).

So I don't think I'd be too worried about you having passed on any negative traits Ambah (IMO, you don't have any such things!). Aidyn seems like such a lovely little boy and I don't think being cautious is ever a bad thing anyway.......it shows he is thinking carefully about what he is doing!!
