He's driving me mad! Often if he doesn't get his own way, or is in a temper, he'll start spitting. It's done in a kind of threatening, "im gonna start spitting then" way. It's disgusting and I don't know how to stop him. If we're at home I've started sending him upstairs if he does it, but he doesn't seem to care.
I vaguely remember ds1 doing it, but it was a short lived thing. It's not a learned behavior, where do they get these things from?!
Any tips to make it stop would be great!
