The member of the popular YouTube family reportedly died of natural causes

Rocked by the sudden death of 13-year-old Caleb Logan Bratayley, the Internet is reacting by honoring the web star, who was a member of the popular YouTube family, the Bratayleys.

“Treat every day as if it’s your last. Although I didn’t know Caleb Logan personally, I can tell he was an amazing person,” Vine star Gabe Erwin posted to Twitter in reaction to the shocking.

Erwin is just one of hundreds of fans to send their support to the Bratayleys following Friday’s Instagram announcement about his death on the family’s account.

“[Thursday] at 7:08PM Caleb Logan Bratayley passed away of natural causes,” she wrote in the post, which included a photo of a smiling Caleb hugging one of his sisters. “This has come as a shock to all of us. Words cannot describe how much we will miss him.”

“We know you tune in to watch each day and eagerly anticipate new videos, but ask that you bear with us while we deal with this tragedy as a family,” the post continues.

Over the weekend, the family posted a tribute video to Caleb on their YouTube account, as well as a clip of him the day before his death that shows him eating breakfast, looking groggy but cheerful and talking about his future.

While The Braytayleys privately grieve offline, social networks are filling up with fan-made tributes to Caleb. Vine, Youtube, Twitter and Instagram users are mourning the boy by celebrating his brief life and offering prayers to his family.

“Praying for @Bratayley & crying over the loss of Caleb. We cling to the hope & faith that families are forever!” successful vlogger Shay Carl posted on Twitter along with a photo of his kids watching a Bratayley clip featuring Caleb.
