She is 11, probably hormonal, but no excuse for her rudeness. Mum is separated from her dad and now in (another!) new relationship
There's your answer!
How many new relationships has her mother had since splitting from your granddaughter's father?
It's a difficult age, I've noticed DGD, who's a bit older, becoming rather moody and hormonal when she was such a sunny-natured little girl.
If she's 11, has she just started at senior school too? Thst can be overwhelming. She has a lot to contend with.
She might just be tired.
Cut her some slack, show her you love her whatever, don't quiz her, but be ready to listen. 🙂
