Yes; I have seen this over and over again; especially the children reacts to Iodine in an emotional way (Anger!)
As Andy says; it feels great when over to the other side of iodine.
My youngest one had a fit the other day (quite rare these days); over some issue at the dinner table, involving his elder brother. He screamed out, slammed the door to his room, and then within 10 minutes he came out, apologized for his behaviour, we had a talk about things, and; finished!
Two years ago this procedure would take at least an hour, maybe two or more; and he would NEVER apologize.
