Michelle Duggar may be one of the toughest women in the U.S. Having given birth to 19 children in 21 years, her body has no doubt seen more than its fair share of miles. Now, it appears that it could be time for Duggar to retire, at least from the baby-making portion of her motherhood.

Duggar’s latest pregnancy, in 2011, ended in a miscarriage. The youngest Duggar child, Josie, was born prematurely in 2011. After a short 25-week pregnancy, Josie was born weighing just 22 ounces. At 45 years old, Michelle Duggar is past the age where doctors begin to warn that pregnancies come with serious health risks for both mother and child. It now appears that the Duggar family is considering adoption as an alternative to another pregnancy.

Duggar told People magazine this week that she and her husband, Jim Bob, may adopt children into their overpacked family, saying, “We are open to the idea of adoption.”

Michelle told People that she and her family are praying to their god about adoption, though she makes it clear her children are encouraging them to expand the family further.

The Duggar family are the stars of the TLC reality TV show 19 Kids and Counting. In addition to their 19 children, the Duggars currently have two grandchildren, with more undoubtedly on the way.
