What are the most important nutrituonal considerations in the first year of life?

 

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.
