I'm having a little problem with my 2.5 yo son. He seems to have a little bit of a mean streak, and i don't know if it is normal behavior or not. First, we had his soon to be step siblings over our house on Sunday, a 5yo girl and almost 2yo boy, and he was not happy! He was fine with the girl, played with her and loved her, but with the boy, he didn't want him touching any of his toys (which I know is normal) and at one point took him into my bedroom and tried to hurt him (he pushed him) and that got me worried. How does he even know enough to take him away from the adults to attempt to hurt him??
Also, he is very mean to my sister. She is around him everyday, and she obviously loves him and loves playing with him. But, he has been giving her a hard time. When she comes in the house, he says "I don't like Auntie L" over and over, and he will cry if she tries to go near him. Half the time he does that, and the other half he loves her and kisses her and plays like normal. I know that my sister feels very bad about this, as do I! He doesn't do this with anyone else, just her. Today, when he said he doesn't like auntie, I asked why, and he said because I like Mommy! I told him he can like everyone! I don't know where to go from here.
