so DD was 5 in March, and her rudeness and back chat has got worse and worse over the last 6 months or so.
lots is low level, rude "no!" when I ask her to do something, or stupid mummy, shut up! etc or contradicting me. also a lot of lying to avoid getting into trouble (often about her little sister)
I usually tell her the rudeness isn't acceptable and I don't want to be around her when she's not talking in a kind and loving way and walk away, barring her from the room I'm in if necessary for a few mins and until i get an apology. not always possible if we're in the car or rushing to get out the house.
DH thinks we should be stricter and be putting her on the naughty step every time, I appreciate we can't let her get away with it but I'm worried this will lead to a power struggle and erode our relationship.
advice please!!
