Fight, fight! When new siblings don’t get along.
Jessica’s daughter gets along great with her stepsister who’s about the same age, but the older stepsister wants nothing to do with her. And everyone feels the tension. Respond to sibling conflict by helping them resolve the issue, but when one sibling is holding out or mistreating the other coach them toward love. Call them up to decency and generosity and encourage leadership in older siblings. Help them see the opportunity, not the inconvenience, of being a positive influence.
