In the first 12 months of life a baby will triple its weight and increase its length by 50 per cent. These gains in weight and height are the primary indices of nutritional status and their accurate measure at regular intervals are compared with standard growth charts. These measurements are important tools for monitoring a child's progress particularly during the first 6 to 12 months of life.
Breast-feeding on demand remains the ideal form of feeding for
healthy babies who are born at term. Human milk provides optimum nutrition for
growth and development. The first 4-6 months are a period of very rapid growth,
particularly for the brain, and the amino acid and fatty acid composition of
breast milk is ideally suited to meet those needs. Breast milk also contains
anti-bacterial and anti-infection agents, including immunoglobulins, which have
an important role to play in boosting immune function. The colostrum, which is
the fluid produced by the mammary gland during the first few days after birth,
is rich in protein and has high levels of minerals and vitamins.
Colostrum also contains antibodies, anti-infection agents, anti-inflammatory
factors, growth factors, enzymes and hormones, which are beneficial
for growth and development.
Breast-feeding is strongly advocated for physiological,
psychological and emotional reasons. There is no reason why breast-feeding
should not continue for as long as it is nutritionally satisfactory for mother and
child up to 2 years. However, with changing lifestyles and the availability of
commercially prepared formulae, prepared formulae are generally safe provided
that an approved infant formula is used under strict hygiene conditions. The
infant formulae attempt to mimic as far as possible the composition of human
milk and their use must comply with guidelines laid down by the European Union
and the World Health Organization. Formula-fed infants also need to be demand
fed and the formulae must be made up exactly according to the manufacturer's
instructions for optimal growth. Special attention has to be taken to sterilise
all the feeding equipment to reduce the potential risk of contamination,
because formula-fed babies do not have the same degree of immunological
protection as breast-fed babies.
