Kids are very concerned about what’s FAIR. Especially when it comes to siblings. It’s hard for parents to convince kids that we need new shoes when our shoes wear out or become too small, not when our brother or sister’s shoes wear out. But there are issues that require the same responses from everyone. The house rules apply to everyone. Manners are the same for everyone. Even pets are required to respond to certain manners in the house. Understanding that the rules for pets are different from the rules for them, contributes to understanding that being “fair” is sometimes different for each individual, be it a brother, sister or dog.
