As it turns out, pretty good ones. Because, when they do, a number of positive things can happen. Consider:
They learn to share and cooperate. The one certainty about your child’s life ahead is that it will be filled with interpersonal challenges. There will be no shortage of difficult people and circumstances and countless days filled with situations that require collaborative decision making. Learning the skills of negotiation, compromise and sacrifice now will serve them well in the long run.
They find ways to solve problems through the help of someone other than… you. That’s right. You’re not always going to be there. When you’re not, they need to know how to leverage other people and resources to navigate problems. An easily accessible sibling is like training wheels towards self-reliance.
They’re more inclined to entertain themselves, which plays a huge role in how they develop their interpersonal skills, broaden their creativity, and master a talent painfully lacking in our modern world: the ability to self-edit.
They forge stronger family bonds. While children may prefer the easy road, the hard work of relationship building breeds lasting respect and commitment. Closer siblings are more inclined to model behavior for each other, raise the bar on performance, and hold each other to established family standards.
