My son has just turned 2 and like any small toddler has a short attention span. When we visit my mother he gets bored and acts up sometimes. Last time he tossed one of her DVDs across the room and she got annoyed and said "Go and pick that up and give it to me please" really sternly. Although he did what he was told and my Mum didn't shout at him or anything, he seemed quite scared. She also insists that he says please and thank-you whenever he asks for anything or else he doesn't get what he wants. I've tried to tell my mother that he's only 2 and doesn't really understand but she insists on "good manners, at least when he's in my house". I know she loves both me and her grandson very much, but am I being unreasonable in being a bit hacked off by this?
