Some brief information about World Breastfeeding Week (from the WHO website):
World Breastfeeding Week is celebrated from 1 to 7 August in more than 120 countries to encourage breastfeeding and improve the health of babies around the world. Breastfeeding is the best way to provide newborns with the nutrients they need, according to the World Alliance for Breastfeeding Action, the event coordinator. WHO recommends exclusive breastfeeding until a baby is six months old.
The week commemorates the Innocenti Declaration made by WHO and UNICEF policymakers in August 1990 to protect, promote and support breastfeeding.
They have also put together a concise, and accurate fact slideshow (10 Facts on Breastfeeding).
Wish I had know about it sooner and found out how I could be involved.
