My sister and her husband have three girls ages eight, ten and fourteen. Her husband teases and ridicules the girls unmercifully. He has told them they’re too tall calling them string bean and he’s made fun of their budding breasts. It’s always some form of comment that he thinks is funny but is negative. I cringe when I hear him do this. I hate to butt in but I feel I need to do something, but what? He thinks it’s all a big joke but he’s belittling these girls.
When children are growing up they need to hear the positives about themselves expecially teens because they are often critical of themselves and how they look. You might think about talking to your sister first about your impression of her husband. Maybe she has already spoken to him but without results. It’s hard to tell if he is being cruel or if he really thinks it’s funny.
I know that it might be difficult for you but someone needs to speak up and try to protect these girls. Let your brother-in-law know how it makes you feel when he makes fun of and belittles his girls. It’s important to express your feelings rather than to criticize and blame. He may be totally unaware of how bad he sounds to others or he could get angry and defensive. Your goal is to make him aware of how he sounds and hopefully convince him to stop making his girls feel bad about themselves. I hope that you can make him see how negative his actions are.
