Good nutrition is key to child development, but Unicef is warning 5.6m children will die of malnutrition each year.
Here in Dhaka, Bangladesh, a woman feeds her malnourished child at a Unicef project.
Weighing infants regularly is one way of ensuring problems are detected early.
Unicef says people need to be educated about foods, such as vegetables, which will provide the nutrients they need.
Group talks, street theatre and peer education are used to inform teenagers about eating well.
New mothers at a centre in Nabinagar, Bangladesh, are given blended food to supplement their diet.
