Stays were worn by children, both boys and girls, from the age of 18 months or when they were walking well. The first stays a child wore were "soft" or lightly boned and were never tightly laced. Stays were intended to support and round the soft rib cage. By two or a little older, the stays would be of a heavy linen, boned with pack thread, reeds, wooden splints, or baleen. These stays fostered good posture. Again, the lacing would be gently firm and not cinch or pinch.
