Welcoming baby Josie in December 2009, the family faced numerous complications at the time, including Michelle's preeclampsia diagnosis and Josie's premature birth at 25 weeks.

"A lot of people have asked would we consider having more children after what we went through with Josie…" says Michelle, offering an update on her little one. "That experience was one of the scariest things we have ever walked through as a family. We thank God, and are grateful for the many prayers offered on Josie's behalf. What a miracle she is, our little sunshine, she is doing wonderful!"

Citing a bible verse in their blog entry, Michelle and Jim Bob, 46, say they couldn't be happier with their ever-expanding brood.

"We do not take for granted the wonderful blessings of life that God has bestowed upon us! Many years ago, Jim Bob and I gave this area of our lives to God, allowing Him to grant life as He saw fit," Michelle wrote.
