Teacher by Day..infertility researcher by night

I do firmly believe that God placed me in current job for a reason. At the time, I couldn't tell what that was except for money in our bank. I now truly believe it was to fill my heart with the love of a child. I don't have, or know if I will ever have, children of my own. However, everyday I have 19 who completely depend on me. My husband and I have been trying to grow our family since January 2010. We recently learned that we will have extreme difficulty naturally having a child. We are pursuing some infertility options. Thus being said, I spend my days with a whole class of children who love me, and come home longing to see another face- one that calls me mommy. I do have faith that God will answer our prayers, and one day we will have additions to our family.
