I am fully agreeing with the quote, no matter the age, good nutrition affects how our body functions, and this most specially true in children as good nutrition helps a child develop and grow. Nutrition is vital in providing energy and nutrients in order for their body to function well, especially for newborn their nutrition is vital for them to acquire immunity through breastfeeding.
Of course we should not forget the nutrition of the mother, specially those who are breastfeeding as they are the source of nutrition of infants for the first 6 moths of their live. Good nutrition for the mother will not only entail better nutrition for the baby but also entail better care for the baby as mother will have more energy to care for their baby.
