The first 1,000 days of a human life also known as the Thousand Day Window of Opportunity- is the time spanning roughly between conception and one’s second birthday. More than 1,000,000 new brain connections are formed per second in the first years of a child’s life. 80% of brain development happens before the age two. This is a unique period of opportunity when the foundations of optimum health, growth, and neurodevelopment across the lifespan are established. While the human brain continues to develop and change throughout life, the most rapid period of brain growth and its period of highest plasticity is in the last trimester of pregnancy and the first two years of life.

For the first 6 months, exclusive feeding is beneficial for both the baby and mother. Breastfeeding can be done until the baby is 24 months or beyond (dependent on mother’s choice and baby’s reciprocation). Breast milk is an important source of nutrients and energy for the babies. It can provide half or more than half of an infant’s energy needs between the ages of 6 and 12 months. And also provides one third of energy needs to babies between 12 and 24 months. Breast milk is very important to protect the babies from harmful infections and also reduces the mortality rate in case of malnourishment.

The American Academy of Pediatrics (AAP) recommends introducing complementary foods (i.e., any solid or liquid other than breast milk or infant formula) to infants at approximately age 6 months. Although a consensus on ideal timing is lacking, most experts agree that introduction of complementary foods before age 4 months is too early because of infant gastrointestinal and motor immaturity. In addition, early introduction prevents exclusively breastfed infants from reaching the recommended 6 months of exclusive breastfeeding and might be associated with increased risk for overweight and obesity.

Many women decide on one method before the birth and then change their minds after their baby is born. And many women decide to breastfeed and supplement with formula because they find that is the best choice for their family and their lifestyle. While you're weighing the pros and cons, talk to your doctor or lactation consultant. These health care providers can give you more information about your options and help you make the best decision for your family
