Rachel Luttrell's Maternal Instinct Comes in Handy

Portraying a pregnant woman onscreen wasn't much of a stretch for actress Rachel Luttrell, the 37-year-old Stargate: Atlantis actress tells The Sun. Rachel, mom to 10-month-old Caden Dar, says "it was very easy to dive into all the emotions you have about protecting your child" -- because she was expecting a child at the time, herself!

Caden is the first child for Rachel and her husband, Loyd Bateman.
