A desperate father in the UK has put a call out for a discontinued Tommee Tippee sippy cup that his autistic son drinks exclusively from.

Marc Carter posted on Twitter how his 14-year-old son Ben will only drink from a blue Tommee Tippee two-handled cup that was made in the 1990’s. He has been drinking from the design since he was two years old.

The cups have disintegrated over time and Tommee Tippee no longer make the cup as they don’t have the production tools to make them. The cup is an old design from the 1990’s.

It’s not as simple as introducing Ben to a new cup, as Mr Carter explained.

“These cups are not made anymore, the replacements are all new and fancy, we’ve tried them, Ben throws them at us,” Mr Carter, who posts as @GrumpyCarer, said.

“People say he will drink when he’s thirsty, but two emergency trips to A&E (accident and emergency department) with severe dehydration say otherwise.

“In all honesty we are really worried what will happen if [the cup] falls apart completely.”

Tommee Tippee have offered free postage for anyone who has the old design sitting in a cupboard to help Mr Carter out.

The company has also searched high and low for this cup in their archives.

“We’ve had a dedicated team searching high and low for this particular cup and have not only checked our archives but have been as far as searching through our cupboards,” the company posted.

“So far, we’ve found that the cup was made in the 1990s and was made especially for [pharmacy] Boots.”

Tommee Tippee were able to find one cup and social media users have organized to send Mr Carter enough cups to last a few years.

“The reality is Ben is unlikely to change, so I will need these for the rest of his life. That’s a lot of cups,” he posted in an update.

But the father has been moved to tears by the offers of help around the world since he put his tweet up. The full-time carer to three children never expected his tweet to the get response it has.

“You have genuinely helped us as a family and given Ben the chance to have lots more cups which are so important in his very complicated little life,” he said.

Anyone who has a cup as the one pictured can private message Tommee Tippee on Facebook with an image, to organise for the cup to be sent to Mr Carter.
