A craze is developing where, babies helped by their parents, try hard to make themselves look like their dolls, creating a semblance that they both are twins. When the babies see themselves and their replica-dolls on a mirror, their joy knows no bounds. Made of soft vinyl, these modern dolls are still cheap, as different from the earlier ones which were made from porcelain. Chinese and Bisque dolls were famous in the 19th century, both made with porcelain heads. Made from leather, cloth or wood, the Bisque dolls had no glassy exterior, but had a matte finish looking like a natural skin.
