Here is a practical question: My son Noah is 14 and my daughter Alethea is 11. They play well with my younger two (Perpetua, 7, and Gideon, 3), but Noah and Alethea do not play well together. Sometimes they snipe and jab verbally at each other. They mostly just avoid each other. We try to punish for this. But it still happens. The condition has worsened as we have traveled much and been in tight quarters during traveling as I have moved about looking for medical care. Any advice in how to get brothers and sisters to get along and love one another? Both claim to believe and show grwoth in other areas. But this area still lags behind.
