Katherine and her husband musician Josh Kelley have announced they will soon be welcoming a new baby boy into the family! The couple have two daughters Nancy Leigh (Naleigh) Mi-Eun, 7, and Adalaide Marie Hope, 4, and Katherine took to her personal blog Those Heavenly Days to share the news of her pregnancy.

"Sooooo… the Kelley family received some very exciting news recently and I’ve been dying to share it with you all. We are expecting a third addition to our tribe! It was totally unexpected but thrilling nonetheless. Naleigh and Adalaide are over the moon and can not wait to spoil their new sibling rotten and of course Josh and I are full of high hopes and bubbling anticipation. The whole pregnancy thing is new to me but the thrill of having a baby is not. We’ve known for awhile that we wanted to add to our family and frankly didn’t really care how we chose to do that. We were considering adoption again, fostering, or pregnancy if possible. Seeing as I have never been pregnant and as my OB/GYN reminded me last year, I’m of advanced maternal age, I wasn’t sure pregnancy was even in the cards for us. Turns out it was very much in the cards!

I can’t wait to share my pregnancy experience with you here on Those Heavenly Days and hopefully get some advice from all you experienced gestaters (yes I made that word up). I’ve learned so much already and know there‚Äôs even more to learn as this baby grows. I’ve found some great tricks to combat pregnancy indigestion, apps that have not only kept me informed on the development of our baby but have offered reassurance and relief when I’m feeling nervous or afraid, and great blogs, and books on healthy pregnancy nutrition.

This is truly an amazingly blessed time, waiting for the child you’ve been dreaming of to make their appearance. Though I’ve never been a particularly patient person, my experience of waiting for Naleigh taught me a lot in that department. So I will wait and eagerly anticipate, hopefully with grace, gratitude and a good attitude (ummm pregnancy hormones are real people.) Maybe this time the waiting won’t be so hard because I’ll have all of you to share the laughter, tears and joys of my experience with. So stay tuned… XOXO, KT"

Katherine revealed she had forgotten her glasses and being near sighted could not see the wall mounted screen, so had to wear prescription sunglasses for her sonogram. "Ultimately I was glad I had the sunglasses on so no one would see me crying" she said.
