Expect and prepare for it. Be ready for the opportunity to help. KNOW your child. The best way to help is to see the crisis coming. But you won't see a crisis coming if you don't know your child.
Crisis causes kids to change what they say, how they feel and how they act.
LOVE your child. Kids feel pain in crisis. They need your love, your trust. They need you. But they will not come to you in time of storm if they don't feel your love in calm.
