My DD (12 nearly 13) just horrible to me and DH and her siblings. I try the being nice approach and she is vile to me, I try to strict approach and she is vile to me. She was a challenging toddler so I always thought she might be the same when the teenage hormones kick in. She pushed me when I just came in from the shops. I've stopped saying goodnight to her at bedtime as get a mouth full but I think perhaps I should just keep doing that. Any wise guidance gratefully received. My teenage DS is not this unkind although admittedly challenging in other ways such as not cleaning up after himself and constantly forgetting to his homework.
