The social media post showing the boy’s scars went viral.Saturday, he was in Denver at IT’SUGAR Candy Store, where he got to go on a candy shopping spree with his siblings.Bridger is smiling for a big reason.“Because I like candy,” he said.The 6-year-old who saved his little sister from a dog attack a couple of weeks ago got a candy shopping spree at IT'SUGAR Candy Store in Denver. They are just the latest in a long line of people reaching out to thank him.“It's been surreal," his father, Robert Walker, said. "We never expected this to go viral the way it did. We were literally just hoping for a postcard or a letter or a shout out to boost our little boy's spirits.”Actor Chris Evans promised him a Captain America shield. Fellow Avengers, Tom Holland, and Robert Downey, Jr., reached out, wanting to reward a little, real-life hero.“He's always been protective of his little girl. She's always been his little princess, and she gets annoyed sometimes that he won't leave her alone. So, it didn't surprise us at all that he would jump in the way he did,” his father added.Bridger has received gifts of support from all over the world, but his parents say the attention hasn't gone to his head.The sugar rush may be the latest chapter for this little hero. One, the family is so thankful for.“The world's a good place, and that there are hundreds and thousands and millions of wonderful people in this world,” Robert Walker said.Bridger and his siblings can all share this experience together.“We're close, and this experience has definitely made us closer,” Robert Walker added.KMGH's Sean Towle first reported this story. 1760

YouTube Kids has struggled with disturbing videos, like beloved Disney characters in violent or sexual situations, sneaking past its automated filters.Now the app is adding new settings to give parents more control over what videos their kids can see.The company announced Wednesday an option to filter videos by "approved content only," so parents can whitelist channels and subjects.The effort comes four months after reports called attention to troves of videos with inappropriate themes on the video-sharing site's kid-friendly platform. Content for YouTube Kids is selected from the main YouTube app and screened using machine learning algorithms. But some videos, such as cartoons disguised as age appropriate, slip through the cracks.Once the new setting is turned on, users can pick collections from trusted creators such as PBS and Kidz Bop, or themed collections curated by YouTube Kids itself.YouTube is launching another tool later this year that will let parents choose every video or channel their kid can see in the app."While no system is perfect, we continue to fine-tune, rigorously test and improve our filters for this more open version of our app. And, as always, we encourage parents to block and flag videos for review that they don't think should be in the YouTube Kids app," the company said in a blog post announcing the new features.It's the kind of control parents have been asking for from the popular app, but it also puts the onus on them to filter content. It's a side effect of the way YouTube Kids finds its videos.When a video for children is uploaded to the main YouTube platform, it is not automatically added to the YouTube Kids library. The videos are reviewed by machine learning algorithms to determine whether or not they are appropriate for the app.The automated process -- one YouTube calls very thorough -- can take days. A human doesn't check the videos before they're added, but parents can flag videos they find alarming later and a content reviewer will check it out.However, it's unlikely parents are constantly watching YouTube Kids videos along with their children. It's possible this safety guard isn't sufficient for catching every odd video your kid might see.The flag-the-video-later system has created some problems for the service. Some YouTube creators have uploaded concerning videos marked as kids content that slips past the screening process. These videos have included Spiderman urinating on Frozen's Elsa, Peppa Pig drinking bleach, and Micky Mouse getting run over by a car.The company continues to change its rules to crack down on the issue, but creators are constantly looking for ways to trick the system.YouTube Kids still has its main library available by default for now, and the company says it is working on more controls for parents. 2837

YOSEMITE NATIONAL PARK, Calif. (AP) — No employee or resident has tested positive at Yosemite National Park's health clinic, and no visitors have reported being sick since the park began reopening last month, but tests of the park's raw sewage have confirmed the presence of the virus. Dozens of people are believed to have been infected. The public health officer for Mariposa County, who is overseeing coronavirus testing in the Yosemite area, said the emergence of the coronavirus will not likely lead to policy changes because the park is already following local and state restrictions. Eric Sergienko said he believes the confirmed presence of the virus in Yosemite will make people more vigilant. 710

“Because he was less than 5% chance of survival,” Robert said. Two and a half years ago, Robert's son Brian was in a hotel room with his mom in northern Michigan as his dad fought for custody. She is now in prison because as she used butane hash oil to process marijuana, she caused an explosion, burning 85% of her son’s body.Burn units at hospitals around Michigan said his injuries were too severe. Robert says they didn’t want to admit him and recommended the family just work to ease Brian’s pain. The Shriners Hospital for Children in Boston, however, thought he had a chance, and saved his life. “He is an inspiration," Robert said. "He just had surgery on Friday and he is already off the pain medications."Because Brian has a tracheostomy, he needs his dad with him around the clock in case he has trouble breathing. His father has had to put his career on hold. “The only priority I am focused on is my son’s airway," Robert said. "Right now, my roof is leaking. My kitchen ceiling collapsed. All this crazy stuff is going on. None of that even matters." “That is the size of my actual airway,” said Brian, pointing to an image of his airway. “It's usually that big and it is smaller than a pencil head.”Shriners Hospitals for Children-Boston has covered all of his care, but says it needs to bring in an outside expert that would cost about 0,000 to give him a surgery that would open his airway. If he doesn’t get the operation, scar tissue could close it completely at any time. That would permanently take away his ability to speak. Brian's insurance company was asked to cover that. However, Molina Healthcare repeatedly denied coverage, advising the family there are doctors who can do the procedure in Michigan and in network. 1749
