Looking for some advice/stories, etc..... My 3yo son has become more aggressive lately, maybe past 4 months (note: we have a 3.5 month old and I do think some of this behavior is related to the new baby) and it's really bothering us obviously. At school he will push other kids when he's mad, (and smaller kids for no reason) and he will swat or kick his leg out towards adults when mad. He does this to us at home too. He has a hard time with transitions as well, but that seems pretty normal.

We are going to do an evaluation because we really don't know how best to handle this. He gets super mad and if hes not being physical he is starting to yell, saying No in a nasty tone or saying Stop It. Unfortunately I feel like I'm mostly yelling at him when we are home, especially when it's just me with both kids.

He also is not listening at all. At all. Cue: yelling.

Any advice? Anyone else do some early intervention, etc to tackle this behavior.

Oh at daycare too one of his normal teachers has been out due to a knee surgery, this def hasn't helped as he likes his routine, and there's been one constant teacher but a bunch of others. Not justifying his NOT OK behavior, just trying to figure it out.
