1. Core idea of nutrition and child well-being

  • Nutrition means food at work: the body takes in nutrients and uses them for growth, repair, and well-being.
  • Children need careful nutrition because growth and mental development are rapid.
  • Adequate nutrition supports organs, thinking ability, disease resistance, energy, and positive behaviour.

2. Infancy: feeding, nutrients, and breast feeding

  • Infancy covers birth to 12 months and is marked by very rapid growth.
  • Infants require twice as many calories per kg of body weight as an adult doing heavy work.
  • Breast milk is the best food for infants because it is easily absorbed and nutritionally balanced.

3. Infant nutritional needs and complementary foods

  • Infants need protein for muscular growth, calcium for healthy bones, and iron for blood volume growth.
  • Infant requirements are based on breast milk composition.
  • A well-nourished mother supports the baby’s nutrition through breast milk.
