People tend to just walk away when you throw a tantrum, which makes it completely escalate.
My son could cry loud when he was smaller, oh my and my ex would just let him. Once a neighnour called the police because he refused to give him what he wanted: carry me from the stairs, mom does that too when I wake up.
If you just immediately say: awww sweety, come here with mommy, it's over in 1 minute.
I have a female collegue. If there's too much stress and it doesn't work she curses and stuff so first I'd just go to the toilet, but now I just say: hey Marge, do you need some help?
Whoop and it's over.
