Something you might not know: These toddlers and children are really, really cute!

From the Measles Initiative to the Global Polio Eradication Initiative, numerous programs focus on promoting health and preventing disease in children under the age of 5– especially in the developing world where kids are about 18 times more likely to die before their fifth birthday than children in high-income countries.
