We have a new tantrum trigger in our house. If I have a container of food, and won't give it all to DS2, he loses it. This is ok when it's something small, but when it's a 500g bag of dried cranberries, well, I'm not handing it over.
I've tried decanting an appropriate amount of whatever he wants into a little pot for him. This does not work.
Any other ideas? We had a really nasty tantrum yesterday over a bag of nuts, that I didn't want him to drop all over the street.
