18mo has started having awful physical tantrums where he really hurts us. He knows what he's doing, ie that he will hurt us and that's the intention. The biting is really bad (he's always been a biter, worse when teething) but also now kicking, hitting, getting us by the cheeks and twisting/scratching them etc. He absolutely loses it when he doesn't get his way, to watch the anger that takes him over it's actually quite unsettling. I find myself getting nervous when I know I've got to say no to something, which is ridiculous. I equally try not to say no to everything so he doesn't feel that he's always being controlled, but he's a really active child who gets into everything so it's inevitable that there are some things not possible.
I know tantrums are expected behaviour around this age, but do these sound extreme? I don't see it from his peers to this level.
I try my best to stay calm and say no we don't hit/bite etc, you hurt mummy etc. But I find that increasingly hard with the frequency and hurtfulness of the actions. If anyone else basically started beating me up, you wouldn't stand for it would you?!
Is calm yet firm the best approach? That's my gut instinct but I also don't want to inadvertently be too soft on this behaviour because it feels as though it's getting out of control.
