My sister's children are 12 and 9 and I have been quite free with comments on their behaviour in the past, including telling them off when they are at my house. My ds is now 2 and when he behaves badly my sister shouts at him, reprimands him etc and basically butts in when I am trying to discipline him. I now understand how bloody annoying it must have been when I did this with her children in the past.
How can I explain that I don't want her to reprimand my child without being a total hypocrite?
