You've probably heard that Jed and Katey Duggar, parents of two-and-a-half-year-old Truett Duggar and one-and-a-half-year-old Nora Duggar, are expecting twin girls. Katey is in her third trimester, which means the babies will arrive in three months or less. Jed and Katey recently took a babymoon trip to Cancun and documented it on their YouTube channel.
