Nothing was easy about Desiree Childress’s third pregnancy. Soon after she and her husband, Will, learned they were expecting identical twin boys, she experienced severe nausea. Having trouble holding anything down, she became dehydrated and IV lines for fluids were placed. At about 18 weeks, preterm labor began and strict at-home bed rest prescribed. With two young daughters at home, Tiffany, 9, and Victoria, 5, Desiree found staying off her feet and reducing stress nearly impossible.
