I have lost to baby and my friend come to me ask me if I want her baby I said yes I need to know how to put my name on the brith certificate

You have lost two babies?

And your friend just wants to "give" her baby to you?

You would need to adopt the baby before your name could be put on the birth certificate. See an attorney.

I agree... one does not simply "Give away" a baby... you have to go through the adoption process, which involves the courts and as mentioned you will need an attorney... lots of money... and the fathers agreement.
