A comfort object, more formally a transitional object or attachment object, is an item used to provide psychological comfort, especially in unusual or unique situations, or at bedtime for children. Among toddlers, a comfort object often takes the form of a blanket (called a security blanket) or a stuffed animal toy or some other favorite toy, and may be referred to by a nickname such as blankie. In child psychology In human childhood development, the term transitional object is normally used. It is something, usually a physical object, which takes the place of the mother-child bond. Common examples include dolls, teddy bears or blankets. Donald Woods Winnicott introduced the concepts of transitional objects and transitional experience in reference to a particular developmental sequence. With "transition" Winnicott means an intermediate developmental phase between the psychic and external reality. In this "transitional space" we can find the "transitional object". When the young child begins to separate the "me" from the "not-me" and evolves from complete dependence to a stage of relative independence, it uses transitional objects. Infants see themselves and the mother as a whole. In this phase the mother "brings the world" to the infant without delay which gives it a "moment of illusion", a belief that its own wish creates the object of its desire which brings with it a sense of satisfaction. Winnicott calls this subjective omnipotence. Alongside the subjective omnipotence of a child lies an objective reality, which constitutes the child's awareness of separateness between itself and desired objects. While the subjective omnipotence experience is one in which the child feels that its desires create satisfaction, the objective reality experience is one in which the child independently seeks out objects of desire. Later on the child comes to realize that the mother is a separate entity, which tells the child that they have lost something. The child realizes that they are dependent on others, thus losing the idea that they are independent. This realization creates a difficult period and brings frustration and anxiety with it. The mother cannot always be there to "bring the world" to the baby, a realization which has a powerful, somewhat painful, but ultimately constructive impact on the child. Through fantasizing about the object of its wishes the child will find comfort. A transitional object can be used in this process. The transitional object is often the first "not me" possession that really belongs
