Tyreek Hill‘s eight-month-old daughter was taken to the emergency room on Wednesday after showing symptoms that raised concerns … but, thankfully, the baby’s mom says the little girl’s improving.

Keeta Vaccaro — Tyreek’s estranged wife — shared the scary details of the incident on her Instagram page on Thursday … writing her doctor advised her to get to a hospital ASAP on Wednesday night after baby Capri “started feeling warm, super sleepy, and just not herself.”

“I called [Dr. Jared Friedman],” Keeta said, “and within minutes, he had us straight into the ER with an incredible team waiting for us.”

Keeta said Capri went through a bunch of tests … and, fortunately, it looks like her baby girl is going to be OK.

“She’s doing much better today 💖,” she wrote.

Hill did miss Dolphins practice on Wednesday … but the team said it was due to an “undisclosed injury.” He was seen later in the day boarding a plane for Miami’s upcoming road preseason matchup with the Bears.

Hill and Vaccaro’s daughter was born last November, a year after they got married.
