After I told her she was my hero, she said I know, so I asked what’s you’re superhero name and she spoke her last words, “Super Sydney” as she raised her arm in the air, like she was flying!

Thank you all for your love and support. We will post arrangements as soon as we have them finalized. We now have to spend some time focusing on her siblings and ourselves, and learn how to be a family in this new normal. Nothing will ever be the same again.
