Carrying the baby in comfort . A London nursemaid has an ingenious device to relieve arm strain when she takes her charge for his morning walk in the Park . the baby is carried in the arms in the ordinary manner , but is suspended in a strong ' hammock ' , which is in turn attached to a broad strap running over the shoulder and under the arm . The weight is evenly distributed over the nurse ' s arms and shoulders and there is no sagging on the part of the baby , who rests quite comfortably and easily in the hammock . Photo shows , taking the baby for his morning walk , using the new device , in the park . 15 March 1936
