The cuddly toy, like the thumb or the pacifier, materializes the link between the baby's internal world and the outside world. This infant goes out to meet what is around him. He finds that the universe he discovers is full of surprises!
The comforter or the pacifier are substitutes that allow him to cope psychologically with the changes. They have the function of reassuring baby. It is for this reason that the majority of the infant's thoughts and activities are centered around what are called transitional objects. Thanks to them, the child can open up more easily to others as they grow up.
