Sibling rivalry was really hard to deal with. You hear a lot of different peoples' opinion on what you should do, like your teacher or your doctor or whoever. And I think it just came down to what was authentic with me, and I had zero tolerance for it. So that's what we decided to do. And I sat down and had a meeting with my girls and I said, "Here's the deal. There's going to be zero tolerance for bullying or being condescending to your siblings." One day I sent my daughter to her room for like four hours, she ate dinner there, she went to bed, we weren't mean, we didn't yell. We just said, "That's the deal. You're taken out of the equation if you're going to be mean to someone in your family." I think I had to do that a couple of times, mostly my older one with the younger ones, and it worked.
