It is now well recognized that very young children, including babies, do experience grief, they just show it differently. When someone familiar dies, the overriding response in the under 5s is a sense of loss. Being too young to understand the cause, and lacking the vocabulary, they express their distress through their behavior. Even a very young baby, with clearly no concept of what being dead means, will pick up on an emotionally charged atmosphere and will probably have a reaction of some sort. When it is a parent or main carer who has died, this loss will be particularly acutely felt through the inevitable changes such as an upset routine, a different carer, and unfamiliar surroundings with strange sounds and smells. A toddler is capable of taking in much more than most adults realize and will be very aware that something significant has happened. Under 5s can, and often do, react strongly to their own grief, but also to the grief of significant adults involved in their day-to-day care.Whatever the circumstances, babies and children under five years of age need to have their grief acknowledged, and their distress comforted.
