If you'd ever told me that I'd be known for SIDS research or breast feeding research or something called co-sleeping, I would have definitely told you that it was a case of mistaken identity. I was a primatologist, studying monkeys and apes in the beginning of my career, publishing many papers on mother-infant relationships, amongst this particular beautiful monkey of North India. But when my lovely wife and I became pregnant, we, like most parents, ran to the bookstores, Barnes and Noble and every other place we could to read about how to become the most perfect parents one could. And after reading all of these works, my wife who is also an anthropologist, were led to one of two conclusions: either everything we had leaned about human development, the evolution of human behavior, parenting and infancy was fallacious coming out of anthropology, or all of the recommendations made by Western pediatricians as to how best to care for infants had really nothing to do with babies at all, and were really based on more recent cultural Western ideologies about who we want babies to become - that is to say independent, separate - the all-American babies rather than who they actually are. And I was really quite appalled by some of the recommendations that somehow without any evidence, empirical, or otherwise, that we all accepted the fact that somehow the humans infant, the most vulnerable baby of all, with neurologically the least maturity and last development of any primate could somehow benefit sleeping down the hall from the parent, because we all know, and the data was showing and I was studying this, that contact of a primate with the mother is much more than a nice social idea; it's fundamental physiology. Contact, changes, the clinical direction of a baby's development in terms of heart rate, body temperature, all kinds of things.
