I have two daughters. One 10 usually polite and well behaved
One 8 nearly 9 usually well behaved but can be extremely rude. Today have had to deal with three bouts of rudeness and angry shouting. Been sent to her room, Easter choc been taken, new pumps been taken and later she repeats similar behaviour. I usually stay calm and explain it is just not acceptable
Advice?! What else can I do?
