Comparing children is possibly the most destructive mistake that parents of two or more children can make. If you have a sibling, how many times did you hear “why can’t you be good, like your sister?” or “your brother is so much easier than you!”? How did it make you feel when your parents compared you to your sibling? Resentful? Hurt? Angry? Not only can comparison drive a wedge between parent and child relationships, but it can also cause animosity between siblings. Labelling children can have similar unexpected negative consequences.
