Feeding practices of infants and young children heavily influence their chances of short-term survival and their capacity to realise their long-term potential. They contribute to healthy growth, decrease rates of stunting and obesity and lead to higher intellectual development (Victora et al., 2016[1]). Starting at the beginning of a woman’s pregnancy to the second birthday of her child, the first 1 000 days represent a key opportunity to ensure wellness and create the foundations of a productive and healthy life. Breastfeeding is often the best way to provide nutrition for infants. Breast milk provides infants with nutrients they need for healthy development, including the antibodies that help protect them from common childhood illnesses such as diarrhoea and pneumonia, the two primary causes of child mortality worldwide (see indicators on “Child mortality” in Chapter 3). Breastfeeding is also linked with better health outcomes as children grow older (Rollins et al., 2016[2]).
