Self Comforting is the ability to calm one's self when faced with a stressful situation, or when in a state of high arousal. The ability to comfort one's self, or to self-soothe, is learned from infancy by interacting with a caregiver who gives the baby soothing and comforting experiences. It is part of self-regulation, or the ability to control one's behavior, emotions, and mental state.
For a baby, self-comforting could include behaviors like thumbsucking or snuggling with a blankie. Some examples of self-comforting behaviors that adults engage in include meditation, going to the spa, taking a walk, or practicing a hobby.
