A device measures the greater extension of the feet from the head by interrupting a beam with the feet when the baby makes an automatic stretching movement. Pref. the measuring device covers a given zone and the head stop can be adjusted into several parallel positions according to the babies size, the measuring device is set to take this into account. A beam is sent across the table from a transmitter on one side of the table to a receiver on he other side and the beam is moved rapidly along the table in cycles at right angles to the head stop. A calculator indicates the position of the next beam arriving at the stop unbroken by the infant's lower limbs.
