Alternative names for Max

Sara • I'm a part-time student studying Naturopathy, I work part-time, I have a 7yr old and am getting married in October!
My gorgeous 7 yo son has told everyone the baby's name is Max (not sure where he pulled that from, it wasn't even on the list haha) it has begun to stick but I don't like Maxwell or Maximillian for the full name. I do like Maddox. Any suggestions?
