Anyone else's 4 year old say this a lot? I have recently noticed dd is saying it quite a lot eg she's playing with her sister (2) and I am out of the room or they are out of sight but I can hear them. I hear squabbling so I look around the door - just to check they're not killing each other immediately dd says I didn't do anything. Now normally they just carry on playing so this makes me think she has done something, though I don't want to accuse her when I am unsure. It has happened twice or three times this week and each time I have been stumbled as what to say.
