For many married couples, having children is a huge part of The Plan. But what happens when biology doesn't cooperate, and you're left unable to have kids like you counted on? This week's guests -- The Mayberrys -- have special insight into an issue that affects millions of couples the world over. While they were ultimately able to overcome the hurdles in front of them and get pregnant (after many thousands of dollars spent on medical care), the journey wasn't easy. In fact, there were plenty of times when it was downright scary, and endlessly frustrating. Hopefully their story will provide valuable insight into the quiet suffering of men and women who want to have kids but simply cannot, and how every once in a while, tales like these can have a very happy ending.
