The 42-year-old dad from Devon, UK worries that the consequences will be dire if a replacement is not found before the current cup wears out. 。

In a Twitter post, he explains, "Ben hasn’t drunk at school since the age of five, he doesn’t drink outside of the house so we can’t go anywhere.。

"People say he will drink when he’s thirsty, but two emergency trips to A&E with severe dehydration say otherwise."。

Carter told the BBC that Ben has had the cup he currently uses for three years now, and he only expects it to last for a few more weeks. 。

Carter, whose other two children also have special needs, turned to Twitter for help, and the response has been overwhelming.。

"It has genuinely moved me to tears," he writes in an update,"It's incredible that you all want to help." 。

Support and promising leads have poured in from all corners of the globe as people searched their cupboards for the two-handled plastic cup: 。

Several people have suggested that a 3D printer might provide a longterm solution, too, if a cup can be secured to replicate.。

Tommee Tippee has also responded to Carter's requests. The BBC quotes its global head of consumer experience Sara Scott as saying, "The cup he previously had was a Tommee Tippee cup that we made for Boots in the late 1990s and our team is currently looking through all our archive product samples to see if we have one that's just right for Ben." 。

Around seven of the tiny blue cups have been collected so far, and Carter hopes to stock up to avoid future desperate hunts.  。
