Hi! My niece is 12 and my sis a few years older than me... basically my sis divorced her hubby a few years ago and the kid became a right brat (I used to really like her) but she is just a clone of my sister, makes sarky comments etc and abit sassy. As a member of the family it gets excused as “that’s just how she is - abit sassy”. Since I’ve had a baby tbh I just find her rude. My partner doesn’t wish to come to family events which I think is fine as he will get annoyed about her saying sarky comments about my parenting and calling my baby “boring”. It annoys me so I wouldn’t expect it to not annoy him. I don’t wish to say anything to my sister as she either excuses my nieces behaviour or is really nasty to her or makes her own sarky comments. Anyway, my brother thinks I should tell my sister it bothers me but I would prefer to just limit all interaction. Thoughts?
