When Do Babies Smile on Purpose‪?‬

Is that tiny smile a reflex, a response to comfort, or the first sign your baby recognizes you? This warm, evidence-aware guide follows the changing meaning of infant smiles from the earliest spontaneous expressions through the social smiles that invite connection. Elena Marsh Whitfield explains what babies are practicing at each stage, why timing varies, and how corrected age can matter for babies born early. You will learn how to notice eye contact, shared attention, vocal turns, and familiar voices without turning development into a test or deadline. Clear examples help you distinguish reflexive movements from increasingly purposeful social communication, while respectful guidance addresses smiles that are subtle, delayed, uneven, or absent. The book also offers practical ways to support face-to-face connection during feeding, play, and everyday care, alongside honest advice about when to share concerns with a pediatrician or health visitor. It makes room for temperament, culture, neurodivergence, parental worry, and the many valid ways babies communicate. You will come away better equipped to observe, respond, and enjoy your baby’s developing social world without pressure to perform. Part of The Smile and Happiness Library.
