DS has figured out that if I say he can't have something (it's not that often, but I draw the line at Ben 10 merchandise!) he looks at me now and says he'll ask "Ma" (that's what he calls her because I do). He'll even ask her whilst looking straight at me. So I have to jump in and explain to both of them why he can't have it and why I haven't a)already got it or b)asked my mum to get it for him. But he knows, she has set some dodgy ground rules. And in NZ when we had that awful time with her she used it against me.
