During the measurement of the body length, a large, inept measuring instrument is placed in the incubator. The measurement requires lots of skills and caution of the two nurses. In addition, the baby is exposed to lots of unnecessary stimuli and bacteria which are undesirable for a “healing environment”.
The head circumference is measured using a standard “flexible tape-measure”, albeit shortened. This instrument is too rough, should be sufficiently clean with every measurement and, moreover, the reliability of the measurements is weak.
