Developmental Psychology is a highly specialized field which concentrates on the developing child. Developmental Psychology can be further divided into subspecialties such as Infant Development, Early Childhood Development, and Adolescent Development. Years of research and diligent study has given us a foundation of knowledge and an understanding of the developing child as we have never before had. And with continued and ongoing research our understanding and knowledge is ever increasing. Although not a prerequisite for conception nor should any parent be expected to prep with years of study prior to their child’s birth, it is definitely helpful to have such resources available. These resources can assist in de-mystifying, de-stressing the job of parents and overall make it more manageable. This is the very goal of this material. It is not being written as a dissertation or any formal discourse for presentation. It is written to and for parents simply and straightforwardly to assist them in managing their child’s behavior more effectively and bring more peace and harmony to their families, their homes, and their lives.
