Janet responds to an email from a father who says he and his wife have “done the best we can to follow the principles of positive parenting,” but their 4-year-old has been refusing to follow instructions and often seems to ignore them entirely. His behavior is particularly aggressive around their newborn, so this dad is struggling to find a way to get through to his son.
