YouTube Kids, dubbed as a safer, child-friendly version of the video-sharing site, has been criticised by parents for failing to remove cartoons that contain clips depicting suicide methods on its platform.
During one cartoon, a man appeared on the screen giving instructions on how to commit suicide, she told the Washington Post.
Hess said the doctored "Splatoon" videos are not the only ones pushing dark and potentially unsafe content on social media platforms, particularly on YouTube Kids. One video titled "Monster School: SLENDERMAN HORROR GAME", features a character enacting a school shooting.
Northcott Community Special School in Bransholme, Hull, told parents "nasty challenges" are appearing in the middle of videos which are supposed to show Fortnite gameplay or Peppa Pig. We appreciate people drawing problematic content to our attention, and make it possible for anyone to flag a video.
A recent YouTube video viewed by The Post appears to include a spliced-in scene showing Internet personality Filthy Frank.
Charlie Jones said: "I asked my seven year old last night if she knew who it was and she said "yes it's Momo she comes up when I'm trying to watch Paw Patrol".
"It makes me angry and sad and frustrated", Hess told CNN.
"So anything that's not curated by the parent, we can not just assume they are not going to be viewing things that are 100 percent safe", said Rogers-Wood. Free N. Hess says in her blog.
According to the Washington Post, Andrea Faville, a spokesperson for YouTube, said that the company is working to make sure that its platform is "not used to encourage unsafe behavior and we have strict policies that prohibit videos which promote self-harm".
But recently, several parents have discovered disturbing videos on the site - ones making them question how safe a place it is. She said she found videos glorifying not only suicide but sexual exploitation and abuse, human trafficking, gun violence and domestic violence. Flagged videos are manually reviewed 24/7 and any videos that don't belong in the app are removed.
Though parents should talk to their children about the videos, Kaslow said, YouTube Kids also should address the issue, explaining to children what the videos were and why children should never harm themselves.
"Once someone reports it, it's too late because a kid has already seen it", she said.
"We are always working to improve our systems and to remove violat [ing] content more quickly".
Dr Hess, from Florida, US, has been pushing to have the confronting YouTube clips removed, backed by other parents and child health experts.
"Just be aware of what your children are watching, what they are saying to other children and make sure they are aware of what MoMo might be but that it's not real", says Arnold.
