"I have a sister, so I know-that relationship, it's all about fairness: you want your sibling to have exactly what you have-the same amount of toys, the same number of meatballs on your spaghetti, the same share of love. But being a mother is completely different. You want your child to have more than you ever did. You want to build a fire underneath her and watch her soar. It's bigger than words."
