Doctors are calling for newborn babies to be given vitamin D, to protect them from bone disease and other illnesses.
The chief medical officer for England wrote to doctors, nurses, and other health professionals, advising them to consider vitamin D supplementation for certain at risk groups- including pregnant mothers.
However, many health professionals say the guidelines do not go far enough.
