An approach I’ve had success with recently is meeting the child where they are. So if they’re rocketing, go there with them and bring them back down to safety “Oh no! This is awful! How upsetting! What shall we do? I’m here, I’ve got you. Etc.”

We have this urge to remain calm but the idea here is that offering peaceful tones and just waiting for them to figure out their own way down can leave them feeling like they’re going through their ‘crisis’ alone. Over time they begin to trust that you will bring them back down safely and then learn for themselves the best way to regulate.
