Kaitlin Hartman was told as a teenager that her chances of ever getting pregnant were not good because of a hormone imbalance.

Years later, she and her husband, Josh Hartman, decided to try with fertility treatments.

When they finally learned they were pregnant, an ultrasound indicated three babies. That was a shock. The next week, the technician made a correction: There were actually four babies. It was going to be a rough pregnancy, but the Hartmans were resolved to face the challenge.

At 21 weeks, doctors were worried that one of the babies was trying to push through. So Kaitlin lived for 67 days with her feet 10-12 degrees above her head to ease the pressure on her cervix.
