Hugs to you Tegan. It must be especially hard with a baby as well.

Jack has started tanties too but I'm really lucky he hasn't had any bad ones yet (knock on wood). With Jack I can usually distract him out of it. But if that doesn't work or I don't get the chance, I tell him that he can have a cuddle when he stops crying - usually it takes about 30 seconds and then he stops crying and comes for a cuddle. In the meantime I tell him that I'm ignoring him until he stops crying and I do ignore him. As I say he doesn't have bad tanties (yet LOL) so this might not help you.

I Really hope it gets better for you. I know Christy has had success with individual PPP counselling when Matilda was tantruming, maybe you could look into that?
