I guess there might be some nuances depending on what the main triggers are. Do you notice any patterns other than when doesn’t get their own way? Or any times they don’t get their own way and do cope?
Two things you can try: mirroring and modelling. Mirroring is when you mirror the child’s emotions back to them, so telling them “I think you’re feeling angry” or “oh I can see your stomping, are you feeling cross?”. This can just start giving them the language so they can help let you know with words.
Modelling is when you show the child the behaviour you want to see. So, if you’re feeling angry, saying “oh this traffic is making mummy so angry, I think I will have to do some calm breathing”. Or whatever it is that helps you cope!
We just got a book from the library called “Mad” which is a really helpful way of naming the feeling in a fun way, and gives lots of redirection activities!
Anger is a tricky feeling because we often have our own reactions to anger. So it can also help to think about what anger brings up for you and your partner, or how anger usually shows itself at home.
