I have a gorgeous 3yo boy who I adore. He is pretty easy when he is with us. He has never been a tantrum child and is so sweet. However, he is really aggressive with other kids. He will hit, push, bite kids he knows and occasionally strangers in the park. He is a happy kid, there is no violence or stress at home, he doesn’t watch any tv except Topsy and Tim/wooly and Tig and no other screens. I don’t know where this aggression comes from. I think it’s mainly impulse control and it’s worse when he is tired or overstimulated. What’s worse is that he laughs when he is being told off like he just doesn’t care. I love him so much but am so worried it will escalate when he starts school. Any advice appreciated x
