My wife and I are avid DIYers — we prefer to do things ourselves rather than calling in outside help. So we defaulted to trying to solve the problem of our son’s outbursts on our own. We were certain we could handle the problem so long as we could find a place to start. I reached out to psychologist Dr. Alan Kazdin, the director of the Yale Parenting Center, and the smartest person I know on issues related to child discipline. He directed me to an online course “Everyday Parenting: The ABCs of Child Rearing”.
