After seeing one of my employees break down this week because he found out (after more than a year) that "his" son wasn't his child at all but from another father we had a little discussion about the subject. One thing we (men) could agree about was that a blood test should be standard procedure at birth.
This can prevent future problems in the relationship and even more importantly: it can prevent a messed up childhood for the child.
What do you think, should a blood test be a standard procedure at birth to confirm the father is indeed the biological father?
