As a parent of multiple children, something you're going to notice during your divorce is that they have different ways of coping. One child might act out, and the other child might become reserved or quiet. One may be sad, and the other may become reckless.
It's hard to know exactly how your kids will respond to divorce, but the one thing that is certain is that you need to take the time to talk to them about the divorce and how it will affect them. Being clear about what is going to happen is a good way to give your kids a chance to explore that future and to start coping with changes as they arise.
