I should know the answer to this, but I've written it out a million ways and it never looks right. I'm putting together D's birth announcement, and the commas in this sentence are driving me crazy! Which is correct?

Welcomed home by proud parents, C and A, and big brother, L.
or
Welcomed home by proud parents C and A and big brother L.

Or is there some option I'm not seeing? I feel like the first option has too many commas and the second option has too few. This is stupid but this was the fastest way I could think of to get a definitive answer since google wasn't helpful.
