A child positioning apparatus for X-ray photography having improved adjustment mechanisms. In particular the positioning of the X-ray film cassette has been improved by using a friction fastner. The friction fastner passes through a groove in the vertical portion of a L-bracket and attaches to a tray for holding the X-ray film. The position of the tray is adjusted by loosening the friction fastener, positioning the tray and then re-tightening to fix the X-ray film cassette into place.
