All info was provided Amy Sanders at Lizzie McGuire Wiki
Amy Sanders is Kate's eighteen-year-old cousin. She is in a band and is not very responsible. She is practically like an older version of Kate, but only far more self centered and immature.
Kate and Amy seem to have a rocky relationship, because in the episode "Party Over Here" she invited only her own friends who proceeded to deliberatly break stuff, ignored Kats request for a chocolate birthday cake because she liked strawberry, and she didn't even know that it was Kate's birthday to which all she does is wish Kate a happy birthday before going off back to the party. Kate is shown to be a lot nicer and mature than Amy despite Amy being older. Amy also appeared in "Clue-Less" and "Xtreme Xmas".
