Michelle and Jim Bob Duggar are expecting their 20th child. Wikipedia features the family:
The Duggars raise their children using a buddy system, wherein an older sibling is assigned to a younger sibling and assists in their primary care. According to Michelle, "they help them with their little phonics lessons and games during the day and help them practice their music lessons. They will play with them or help them pick out the color of their outfit that day and just all of those types of things." In 2004, Michelle Duggar won the "Young Mother of the Year Award" in Arkansas, which is sponsored by American Mothers Incorporated.
In the meantime,
Global Population Speak Out is asking concerned citizens to sign its pledge:
I pledge to show I care about people and planet by taking part in the global discussion about population growth. I am joining the Population 7 Billion: It’s Time to Talk campaign. With world population set to surpass the 7 billion mark in October 2011, it’s time for a broader public discussion, especially about the importance of family planning and the role that educating girls and empowering women can play in creating a healthier and more sustainable world. As part of my pledge, I will start conversations with others and help spread the word.
