I have 3 small children, my 4 year old has always had out of this world melt downs and turns blue with them. My other two have melt downs but never to this severity and we can always calm them down and bring them back round. Nothing I try works with my 4 year old. I’ve done hugging, saying mummy’s hear with you, stroking, tried hand starfish breathing with fingers (tried this when he’s in a good place so he knows how to do it when he’s upset) etc. I’m at a beaten down loss as to what to do as I hate seeing him in such a state. It’s always over the usual toddler things that he melts down but like I said you can’t snap him out of it, goes blue, hyperventilates, gets terrible headaches and tummy aches from the melt down. Any things you can suggest???
