Every now and then, we hear a story about a parent that has exhausted all resources and turns to the internet in a desperate attempt to source a discontinued piece of clothing, impossible to source dolls, and most recently, a sippy cup that happened to be the only cup 14-year-old Ben, a young man with severe autism, would drink out of.

It all started when Ben's father, Marc, took to Twitter with a plea to find a replacement cup after the one they've had in their house since Ben was 2 broke.

"These cups are not made anymore, the replacements are new and fancy, we've tried them, Ben throws them at us. Maybe you have one stuck at the back of a cupboard," Marc wrote. "It can be used, that's fine, the one he has doesn't have long left. In all honesty, we are really worried what will happen if it falls apart completely."

The responses were overwhelming and led to the #CupForBen movement being formed.

It eventually caught the attention of the manufacturer, and they began rummaging through boxes.

We're still on the case BUT we now know it's a cup made for @BootsUK 10+ years ago. We thought this might help everyone's search #CupForBen — tommee tippee UK (@tommeetippee_UK) November 15, 2016

Roughly a week later, Marc posted a video to YouTube to thank everyone and fill them in on some amazing news; that Tommee Tippee was able to find the original mold for the sippy cup in a factory in China, and that they would make 'as many cups as Ben will ever need.'

They've begun manufacturing 500 cups, putting an end to Marc's worries about making sure Ben wouldn't stop drinking and touching the hearts of all those that have been following the story since the original tweet went viral.

The cup production was also down to the overwhelming love and support shown across social channels, so BIG THANKS to you all too. #CupForBen pic.twitter.com/CRd26AGOji — tommee tippee UK (@tommeetippee_UK) November 29, 2016

People commended Tommee Tippee for really going the extra mile in helping the family out.
