My son has been incarcerated since May 10,
2007

A girl he had dated
is pregnant and says that the baby is his.
The first due date she gave me was
Valentine's Day

But then it
switched to Leap Year, and now it's not
til the first week of March. According to
the pregnancy calendar, on 2/14 she would
have conceived late May. Is there ANY
possible way I could be this child's
biological grandmother??
