The mirror is one of the basic accessories for the child in his/her play area. The mirror encourages the babies to observe and explore. We put it in the baby’s play area so that the baby can observe himself/herself while lying. The baby will observe the movement of his/her arms and legs and changes on his/her face with enthusiasm. When the child starts walking, we put the mirror in the vertical position and the child can continue with observing his/her body.
