Kids aren't all the same. You can't follow instructions and expect success every time. So what if parents approached their children as questions to be answered and not problems to be solved? Scientist Emma Byrne takes evidence-based information on everything from physical and emotional development to what is really happening during sleep and separation anxiety, then shows how to apply it to the unique child in front of you. She challenges perceived wisdom by focusing on the variance as well as the mean - because your child is an individual, not an average.
