Please excuse the grammar pedantry, but you've got something odd going on with pronouns. He wants to provide a girl whose DNA comes from Nina with a happy child

Please excuse the grammar pedantry, but you've got something odd going on with pronouns. He wants to provide a girl whose DNA comes from Nina with a happy childhood which Nina did not have. If I were a clone, I would be pretty miffed when people confuse me with my DNA donor, even if it's just a typo. :-)
