I was a foster mom once when my daughter was 5.  It broke my heart to send that baby back after being in our home for 3 months. After one week I felt he was mine.   I did try to adopt that way.  But  I couldn't bear to do it again.   Thus only one adopted child for us.  And she is pro-life, too.   She has not asked us about her parents, but I told her I would help her find them if she ever wanted to see them.
