Look at this picture, shows a little boy who was sleeping on his mother. But can you notice the "huge red flag"?
The little one was considered naughty and, as so often happens these days, he was believed to suffer from ADHD.
But his curious mother read something and she found a new light on this image.
It's his mouth, it's open. He breaths through his mouth during sleep.
Melody Yazdani shared her boyfriend's photo in hopes of helping thousands of other parents whose children have behavioral problems.
She posted the photo of her sleeping son on Facebook on October 24, telling her parents that she would "change her life."
She wrote: "All parents. If you have a child, I'll tell you something you need to know that you probably never heard of.
"There is a huge red flag in the image I share with this story. Do you see it?"
Mother explained how last year, her son, Kian, who is eight years old, began receiving school behavior reports.
She had no problems in kindergarten, and she was always "smart, feisty and extremely active," so Melody was surprised when Kian's teacher told her he was pushing other kids and "she had a hard time controlling her body ".
With new systems at school, his behavior has improved – but home worsened, with drops on small things.
"Every morning is the tantrum after the tantrum before we get out of bed," she said. "He hit and throw things, and screaming, all screaming, starting at 5 o'clock in the morning.
"I was in a loss – how did he become that way, what could we do differently?"
The mirror reports how Kian began to see a therapist who recommended testing ADHD.
"Lightning struck" when Melody found an article linking ADHD to sleep disordered breathing and breathing of the mouth.
The red flag in Melody's photo is that Kian's mouth is open while he's asleep.
She wrote: "Children should NOT come back through their eyes, not while they wake up, not during the fall.
"Breathing in the mouth is NOT NORMAL and has long-term consequences on health. I will repeat, because this is important – HUMAN RESTORATION IS NOT NORMAL, NOT IN DAY OR NECESSARY.
"When a child breathes through the mouth, the brain (and body) does not get enough oxygen. At night, this decrease in oxygen saturation is detrimental to the quality of sleep and the ability of the brain to rest enough."
The song mentions other problems that may cause breathing on the mouth before explaining that sleep deprivation in children and ADHD have "exactly the same symptoms".
She claims that studies with children with ADHD medications in which their respiration was fixed showed an improvement in symptoms and that within 70 months 70% of the children were no longer medicated.
"As with their case, their ADHD has been cured, because it was not ADHD, in 70% of the children, let them sink," she wrote.
Kian was diagnosed with sleep apnea and sinusitis.
"He had exactly 0 minutes of REM sleep during the first study and oxygen saturation decreased by 80%, and his sinuses were blocked at 90%," Melody explained.
"I had no idea that Kian had a headache everyday, but it was just normal, so he never thought to tell us."
My mother noticed an "immediate change" when Kian's tonsils and adenoids were removed, breathing through the nose when she left the surgery.
"I saw a complete plot of 180 (sic)," she wrote. "Without angry annoyances, no fixation of small OCD things, it was an enormous change.
"That's why I share: Nobody, in my 12-year-old parents, has ever told me about it.
"All the signs were there, right in front of our eyes, and I had no idea."
