Kim and Kanye's son Saint West was recently rushed to the hospital after suffering an allergic reaction.
Kim's mom Kris talked about the ordeal on a recent KUWTK episode when she was asked about her most recent late-night call.
"We discovered he might be allergic to grass," Kris recalled.
"We ended up in the E.R. but all is well - we figured it out."
This isn't the first time Kris panicked as a grandmother. She also revealed Mason, Kourtney Kardashian and Scott Disick's 9-year-old son, was once taken to the hospital after suffering an allergic reaction to peanut butter.
She added: "The first one I ever got was the most alarming. It was when Mason ate peanut butter and his face started blowing up and his throat started closing.
"They had to rush him to the hospital. He had a peanut butter allergy for the longest time. He's fine now. The scariest is always the first time."
I honestly love the Kardashian and Jenner kids so much, they're the cutest!
