A Texas mom found herself flooded with messages on social media urging her to seek help after posting a picture of her eldest daughter online.

Kiely Branch is raising four children under 5 while preparing to welcome a fifth. Like many parents with young children, Branch enjoys documenting the highs, lows, and hilarity of family life on social media.

"Life in our house is definitely never boring," she told Newsweek.

According to a 2021 Security.org survey, 77 percent of U.S. parents have shared photos, videos, or stories about their children on social media, highlighting how common "sharenting" has become.

However, one of Branch's recent TikTok posts featuring her 4-year-old daughter took an unexpected turn when she found herself flooded with messages from users advising her to seek medical advice. It was all because of one specific facial feature.

"The post actually wasn't doing very well initially," Branch said. "The views were extremely low, and I even considered deleting it one night. Then I woke up the next morning and it had completely taken off."

Branch didn't understand why until she started reading the comments.

"I had no idea why until I started reading the comments," she said. "A surprising number of people were telling me that I needed to have my daughter checked for a particular genetic condition because of her eyebrows."

At first, Branch didn't think much of it. She'd been posting on social media long enough to know that viral posts often generate a mix of opinions and unsolicited advice. But she quickly realized this was different.

"I started seeing comments from other mothers telling me that I needed to take her to her pediatrician 'before it was too late,' and that's when I started finding the whole thing a little more frustrating," Branch said.

She decided to investigate further.

"People were suggesting a genetic condition called Sanfilippo syndrome because they felt that her dark, full eyebrows were a symptom," Branch said.

Sanfilippo syndrome, or mucopolysaccharidosis type III (MPS III), is a rare inherited disorder that prevents the body from properly breaking down certain sugar molecules, leading to progressive damage, particularly in the brain and nervous system.

Symptoms often appear in early childhood and can include developmental delays, speech difficulties, and behavioral problems. Some children may also develop physical features such as prominent eyebrows and a broad forehead, though thick eyebrows alone are not a sign of the condition.

Branch could barely believe what she was reading.

"What made it especially strange to me was that her eyebrows aren't unusual in our family," she said. "They're dark and full, but they're not coarse, and both her father and I naturally have very full eyebrows. Unibrows, actually. Her father and I joke that our kids were genetically destined to have thick eyebrows and potentially unibrows if we don't groom them."

Branch nevertheless decided to learn more about Sanfilippo syndrome. Her daughter had none of the other characteristics or developmental concerns associated with the condition.

"My daughter doesn't have the issues people were assuming she had," Branch said. "She's never had an ear infection, doesn't have the GI issues people were mentioning, sleeps extremely well, and we've never had concerns raised about her head circumference or development by her pediatrician or any of the other medical professionals who have cared for her."

It all made for a strange experience, with Branch finding it "pretty wild" that people could diagnose her daughter "from two photographs."

"Imagine walking into the pediatrician's office and saying, 'Hi, TikTok told me my daughter has a genetic disorder because of her eyebrows. She isn't showing any other symptoms, but can you check her out?'" she said. "As the comments became more aggressive, especially the ones implying that I was neglecting my daughter by not taking her to a doctor, I did get frustrated."

On balance, though, it has made for a unique online experience.

"It has been really interesting, and sometimes hilarious, watching the internet try to figure out a child they've never met from two photographs," Branch said.
