A Brooklyn mother is suing over a cup of scalding tea that she claims severely burned her infant son at a Starbucks.

Villona Maryash claims the tea was “improperly served” without a protective sleeve.

Maryash’s suit, filed in Brooklyn Supreme Court yesterday, stems from an incident last Oct. 9 at the Bensonhurst Starbucks. Her 5-month-old son, Arnold Glouchko, was next to her in a stroller.

While she waited for the rest of her food order, she went to take a sip of the tea, she said.

When she picked up the cup, it was so hot that she dropped it, and the contents spilled over her son, causing “serious injuries,” said her lawyer, Martin Garfield.

He said the tea should have been served on a tray and with an insulating sleeve.

“This cup was improperly served, and that’s the reason my client dropped it on her baby,” he said.

There was no immediate comment from Starbucks.

In May a Manhattan customer sued Starbucks for serving him “unreasonably hot” tea in a container that was “not safe. He claimed he suffered “great physical pain and mental anguish.”
