If DNA testing is done at birth, for all babies, then disputes over who is biologically and legally responsible for a child will be stopped before they can start. There are so many men out there who have lived their lives believing they are biologically the father or a child/ren, only to find that their partner hasn't exactly been as faithful as first thought. Often, the woman has knowingly let the duped father believe he's the dad in order to ensure that someone, anyone, is being financially responsible for the child. In any family breakdown, the child is always going to be the one who suffers, so DNA testing at birth would ensure the truth is known and unable to be hidden from the child.

I do firmly believe though, that their is a difference between a father and a dad. Dad is the person who is there for a child, biologically connected or not- Father is just the sperm donor, who may or may not become Dad.

P.S. There is no doubt Les has fathered our 5 girls, they are just as cheeky and mischievious as thier Father and Dad.
