The 3 Most Shocking Twins(Multiples) Stories of 2009

Woman Gives Birth to Two Babies, Not Twins

Julia Grovenburg and her husband, Todd, were shocked when doctors told them Julia was pregnant with not one, but two babies.
 
But even more shocking was the fact that these babies were not conceived on the same day, and therefore, were not twins.
 
This rare occurrence is known as superfetation and it happens when the mother conceives a child while pregnant with another.
 
Dr. Karen Boyle of the Greater Baltimore Medical Center told ABC News she has only heard of 10 reported cases of superfetation.
 
Doctors think Julia conceived baby girl Jillian first, and her brother, Hudson, two-and-a-half weeks later.
