An infantometer is made of low-friction styrene, has two telescoping halves, with each having half of the measuring indicia thereon. The first stationary half has a fixed handle against which the head of the infant is placed. The measuring indicia or scale on the first half is located along one side edge thereof. The second, sliding half telescopingly slides in the first fixed half, and has a fixed foot-handle attached at it distal, free end for abutment against the feet of the outstretched infant. The measuring indicia or scale on the second half is located along a side edge thereof laterally opposite to that corresponding to the first half. The measuring indicia on the second half is arranged in descending order of magnitude, so that the free end-edge of the first half serves as a indication-rule. The two halves have an upper surface that form a trough or concave central section on which the infant is supported, whereby the infant is prevented from falling out. |
