When a human child learns to walk, the term toddler may be used instead. The term infant is typically applied to young children between the ages of 1 month and 12 months; however, definitions may vary between birth and 1 year of age, or even between birth and 2 years of age. A newborn is an infant who is only hours, days, or up to a few weeks old.
Infant mortality is the death of a child less than one year of age. It is measured as infant mortality rate (IMR), which is the number of deaths of children under one year of age per 1000 live births. The leading causes of infant mortality are birth asphyxia, pneumonia, pre-term birth complications, diarrhoea, malaria, measles and malnutrition.
