When do you know if something is normal toddler behaviour and when it’s a cause for concern?
My 3 year old hits, kicks, slaps myself, his dad, and his 1 year old sister. He also tries to sit on her back, push her down, repeatedly slam her head against the floor when she’s sitting down, poke her eyes. He doesn’t care when she starts crying, he doesn’t stop - even when he is told off or put in his room to calm down. It’s always unprovoked as well, she’ll be sitting next to him or doing her own things and he’ll go to her whenever we have our backs turned.
