3-in-1 bed woodworking plan. Like a best friend, this bed grows up with your child. Starting as a crib for a newborn, this 'sleep System” easily changes into a bed for a toddler, and then into a full bed, serving a child well past adolescence. Simple decorative connector bolts and concealed cross dowels make these quick changes possible. Build all the parts now and be years ahead, or choose any one of the three beds to meet current needs.
