Well, I don't really try anymore.
She's entitled to her big moods as much as I am. I understand I might not wail and get sweaty and become disregulated but she does because she's a child.
We used to try and dampen the big blow ups by going to sit in her room with her and closing the door but actually that was us trying to reduce the noise/disruption for our own needs- peace.
DD has been diagnosed with autism at 10 and we have learned that she needs to guide us. So sometimes it's shouting, sometimes it's screaming into a pillow. Sometimes I give her some kitchen roll to tear up, sometimes she wants a hug and sometimes she wants space. Sometimes she needs fresh air or exercise.
So now that she's older she can tell us what she needs and a lot of time we ask her to try and be specific about physical feelings.
'Is it in you stomach or a headache' food, drink may help).
Are you too hot? (Take some clothes off, open a window)
Buzzing in your ears (music or silence)
Do you need physical comfort (a hug)
Do you feel full of beans (let's go for a walk)
Most of all it was reading the Phillippa Perry book about how by wanting our child to calm down, sometimes that's for our own comfort. Of course we have needs too and sometimes children can't be the best at explaining how they feel but we can help them.
