The first 1,000 days, or the thousand day window of opportunity, is recognized as the time between a woman’s pregnancy and her child’s second birthday. It is the most critical period of growth and development in a child’s life, hence the importance of good nutrition during this period for both the child and mother. 

Proper nutrition during this period provides the essential building blocks for brain development, healthy growth and a strong immune system. No amount of food can cure a stunted child: good nutrition must start early to prevent stunting before it starts.
