Safety and dignity first: move to a quieter corner if possible, lower your voice, reduce your words, and don’t demand eye contact or apologies mid-meltdown. Carry a small “calm kit” (headphones, favourite fidget, water, a snack). Afterwards, look for the trigger — noise, crowd, hunger, transition — and plan around it next time (visit off-peak, preview the outing with photos, agree an exit signal). A meltdown is overload, not misbehaviour; punishment makes the next one more likely, preparation makes it less.
