My ds, now 9, was a pretty aggressive guy as a toddler, and for several years after. For instance, if he wanted to give you a hug, he would run at you, full throttle, practically knock you over or bang into you hard to deliver the 'hug'. It was disconcerting. Also, in play, he is very hands-on wants to hug people, preferring more physical contact than most kids it seems.
That reminds me of when DD5 was 3. When he was in preschool they were saying he was "aggressive" with peers. I asked them to clarify this as he was such a caring non-aggressive kid. They said he was hugging on kids and running around playing tag a lot. And that sometimes he would hug kids even when they didn't want hugs. They then said "he isn't trying to hurt anyone" I said "well that doesn't sound like aggressive then." seriously? unwanted hugs is aggressive?
otherwise DS can be intense and has overexcitabilities. Used to be incredibly sound sensitive but is better with that for the most part. He can get emotional at times, doesn't really get angry much and has a good mood and is easy going. But will get upset if he loses things, or messes something up, etc. Just a minute ago he lost a game of battleship against DH and started to cry. He said emotionally "I am sorry dad, I will try to do better next time....I don't know why my eyes are starting to water, this happens to me all the time and it is really bothering me because I don't know why it is happening" DH says "you did great buddy and it is just because you are disappointed, which is fine...it's okay to get disappointed when you don't win and sometimes you get watery eyes too which is okay" It is probably also because he is overtired because he certainly doesn't cry or get upset every time he loses things. But he does have strong feelings sometimes for sure
