A child in preadolescence is not the same person he was just a year or two ago. He has changed —physically, cognitively, emotionally, and socially. What he may not know is that he needs you as much as ever, because a strong parent-child relationship now can set the stage for a much less turbulent adolescence. We asked some experts for parenting tips to help you keep the channels of communication open between you and your pre-teen —and have a smoother transition into the teen years.

Why are teenagers such moody, lazy, selfish nightmares? We gave readers the chance to ask Frances E Jensen, author of a new book on the adolescent mind, how to deal with these hormonal time bombs. She found that while much had been written about teen psychology and parenting, no one had explained the neurons and cerebral connections that make those years such a unique — and terrifying — part of growing up. The teenage brain has only recently become a subject for serious research, which shows how little was known about it. Without a doubt, says Jensen, who thinks that her research allowed her to be more patient with her sons.
