Hi I need some advice please. My sisters kids are really very rude. There is a big age gap of 15 years between them. The lack of manners and level of rudeness is the same and I'm appealed by it. My sister and my mum treat the youngest who is 7 like she can do no wrong. She talks back like a stroppy teenager. I asked her yesterday to please stop wiping her muddy feet on my new rug. Her response was "make me". When my sister is around she completely ignores this bad behaviour. Same niece is not allowed to play with kids at school, in her street or anywhere in fact be because my sister says other kids keep bullying her. However I think my niece is the Bully! I have seen her treat her friends terribly. I don't like my 5 year old being around her but I can't always avoid it. My son is a typical boy and has no interest in girly squabbles and tell tales. She often it's him and he won't retaliate he simply refuses to play with her until she apologises. However my sister gets super defensive and hugs and kisses her little princess who is being "bullied". She is my niece and I feel awful but I can't stand to be around her. I can't talk to her mum she thinks people are jealous of her little princess. She treated her other daughter this way and she is now 20 and total trouble so you think she would learn. For info Dad's not around much.
