But one thing that is certain for the couple from Arkansas: the full-throated support of their fans.
"My daughter Erin was born prematurely at 25 weeks, weighing 1 lb., 12 oz. She is 23 years old now with a child of her own," Lynne from Virginia writes to the Duggars on the TLC Web site. "You have some very rough days and weeks ahead of you, but with God's help, Josie CAN make it and be a happy, healthy baby. I wish you all the best!"
"Dear Duggars: Fear Not!" writes Candace. "My second grandson was born at 26 weeks, weighed 1l lb., 11 oz. and was 11 inches long. He is now a healthy, happy and normal three year old. You are on a journey that will test your faith, but fear not! Trust God first, the doctors and medical staff second. Josie will be home with you sooner than you think!"
According to TLC, Michelle and baby Josie Brooklyn remain in stable condition. "Michelle is resting comfortably and baby is stable and in the NICU for extended care," TLC says. "The most important thing right now is for Mom and baby Josie to get as much rest as possible. The family is grateful for all the prayers and well wishes during their recovery."
Not all the supporters of the Duggars are parents of preemies – some were preemies themselves.
"I was born a preemie! I weighed 2 lbs., 5 oz. and I was 10 inches long! I did have a few health complications, but now I am 5' 10" and I play four sports (track, soccer, volleyball, and basketball)!" Amy writes in. "I am praying that it all works out for you all! Best Wishes!"
