Is There a Baby in Your Tummy Momma?

Ok... it must be all the time that we are spending together... but yesterday Carson asked me if there was a baby in his tummy. I explained that only girls have babies. He thought for a minute... and asked if I had a baby in my tummy? I told him, "no mommy's tummy was broken and a baby couldn't grow in mine" I could see his mind working... he asked if he grew in my tummy before it was broken... and I told him no...a special lady grew you in her tummy and since she knew you were our little boy... she gave you to us. I tried to explain in five year old language.. that he was adopted. This is the first time this has come up with him, and I have prayed for years the right words to say when it finally was asked. I explained how special he was, because of all the little boys in the whole wide world we got to pick him. He was happy with that answer. I can only hope that as he gets older and the questions become more detailed, that God grants us the right words to say. I have often struggled with the what if questions... you know how come she didn't want me, or why did she keep my brothers and sister? I know that I am most likely worrying about something that is years away.. if it ever comes up!
