Parenting has many seasons to it. If you've got a kid over 20, you know what I mean. Stepparents and foster parents jump into that river mid-stream-while learning to swim at the same time. Reactions like, "my kid never acted like this." Or, "I've never had a teenager before-is this normal?" are common. Hey, it's easy to get lost in the rapids so help each other out. The biological parent can fill in a few gaps while the stepparent plays catch-up. Slow down. Get in sync. And hang on for the ride.
