This isn't the first year for a post like this to go viral, urging not only parents of children with autism to carry the blue buckets, but also those doling out the treats to be aware.

Last year, another woman made a similar post that her 21-year-old son would be taking part in the festivities and asking social media users to "spread awareness."
But the debunking website Snopes.com says don't bank on every child with autism carrying a blue bucket, or every child with a blue bucket has autism.
While the move is gaining popularity on social media, there's no official campaign sponsored by Autism Speaks. Snopes said, "Carrying a blue bucket while trick-or-treating is not a widely recognized symbol for people with autism."
The advocacy group Autism Speaks has a guide for celebrating the holiday with children who have autism. The group does not mention the blue buckets specifically but does have the suggestion of the child wearing a badge or have a sign on their bag that they may not communicate the same way as other children.
The group though did share last year's post leading up to the holiday.
