I had my little girl christened back in September 2009. But in the mean time it has come to my attention that who we thought was the potental father is not, but he attended the christeneing as the father. Now tracking down the really father, he would like to get the little one christened. Does this make the origanal christening invalid as we have had the birth certificate changed and the really father did not attend. Please can someone help me.

Christening is a church activity, and is valid by the rules of that church, Some call it infant baptism, other churches do not even accept the idea of infant baptism or christianing.

For the denominations I know of, the sexual history of the mother and who she thinks or does not think the father is, has nothing to do with the religious act. That is merely between the infant and God and the witnesses who promise to raise the child in that specific denominational teachings.

There is no reason to have a second, many churches would not even do a second if they know there was a first.

Why does the father not accept the first ?
Is this within a different denomination ?

If the pastor does it, it does not make the first void, only gives the child two.

The true father does not accept the baptism as he did not attend the ceremany. The other gentleman attended with his family and his witnesses. The godparent who attend the ceremany have turned there back on the there promise that was made on that day. Therefore the genetical dad wants a baptism with his family and his witnesses there, so our child has some godparents. Some one to look over her as well as us, her parents.

Just because the bio father does not like it, does not mean it is not a valid baptism,

If your pastor or priest will do a second, they may, but the first still is valid also.

That's better and I can see your reasoning but a child is baptise in the eyes of god not their parents. I see no reasoning however for a second baptism to take place if only for people who you love and trust to commit to your child's future.
