Both the World Health Organisation and UNICEF strongly recommend that all babies should be exclusively breast-fed during their first 4 to 6 months of life and thereafter continue to be breast-fed, with a gradual addition of complimentary foods, until at least 2 years of age.
Rickets is characterised by defective mineralisation of growing bone, and it causes skeletal deformities if it occurs during the first few years of life, sometimes leaving permanent sequelae in the musculoskeletal system. The disorder has been known for many centuries but became widespread during the industrial revolution, mainly in Britain; hence its Hungarian name: “English” disease.
Diarrhoea has a negative effect on the growth of children. In developing countries where malnutrition is a major public health problem, recurrent attacks of diarrhoea and other infections make their nutritional status worse. The World Health Organization has recommended that feeding be continued during diarrhoea and that extra food be provided during recovery.
