The layette of the newborn baby remained constant throughout the 19th and early 20th century. Although infants were gradually freed from swaddling clothes, the use of a "binder", a 4-5" wide and up to 30" long band wrapped tightly around the child's abdomen, was still prescribed in the early 20th century. As the "Age of Sensibility" of the early 19th century ended, children were put back in quilted or corded stays, numerous petticoats and underpinnings and progressively longer and fuller gowns. "Napkins" or "nappies" in diaper weave linen (hence the name diapers) were secured with straight pins until the invention of the "safety" pin in 1849. Disposable diapers were invented in the 1890s did not become fully available and affordable until the 1960s. Waterproof rubberized Mackintosh "pilches" (rubber pants) to cover diapers appeared in the late 1890s. New mothers were instructed to buy "a dozen of everything" since laundering was a never-ending, arduous and time-consuming task.
