Kylie Jenner reveals daughter Stormi was hospitalised after allergic reaction

Kylie Jenner experienced one of her first serious scares as a mother over the weekend.

On Monday, the 21-year-old reality star and beauty mogul revealed on social media that she had been in hospital with her one-year-old daughter, Stormi Webster, who she shares with boyfriend Travis Scott.

"Spent the day in the hospital with my baby," she wrote on her Instagram Story. "She had an allergic reaction but is 100% okay now and we are home."

"Nothing else matters when these things happen," she continued. "God bless all the moms with sick babies. I'm sending so much love and positive energy your way."

A source told People that Stormi's health scare seemed to be a "food-related reaction," adding that Jenner was "very scared" for her little girl. "But Stormi is fine."

"Kylie was told to watch Stormi closely," the source said. "She is taking Stormi to her pediatrician for a follow-up."

While Jenner, the world's youngest self-made billionaire, didn't divulge anything more about the incident, she did recently open up about Stormi's palette, revealing the youngster is developing a taste for Japanese food.

"Stormi loves sushi," Jenner said in a vlog shared by her friend Heather Sanders. "I'll take her to Nobu… I don't feed her anything raw, but she just loves edamame. They'll bring the whole thing of edamame. She will not stop until it's all gone. She eats all the edamame."

She added that Stormi will "eat a whole bowl of soy sauce rice".
