Christmas Carol : How has Scrooge's attitude towards family changed as a result of his experience?

As a result of his experience, Scrooge has become a loving, well loved member of the family. He is like a second father to Tiny Tim.

He did it all, and infinitely more; and to Tiny Tim, who did not die, he was a second father. He became as good a friend, as good a master, and as good a man, as the good old city knew, or any other good old city, town, or borough, in the good old world.
