I'm going to tell my daughter she caused her mother her back pains instead of her brother
Why would you lie to her?
It is better to blame a girl than a boy.
It is wrong to lie to kids to make one feel bad. You should teach your children honesty so that they can be honest with you.
I'm going to make her dislike her brother, he's such a bitch. I'll never accept a girl rather than a boy.
It is not good to create a problem between siblings. They should be there for each other not fighting all the time. Especially if they didn't do anything to each other and it was just caused by you.
