The baby is now a year old and healthy.
A four-week-old baby is seen breathing strangely in this video, posted online as a cautionary lesson for other parents.
Little Luna can be seen “sucking in” at the ribs – a sign to take your child to a hospital says mum and radio presenter Charlie O’Brien.

The video, viewed more than 1.5 million times, was filmed more than a year ago, and today Luna is a healthy one-year-old, but she actually had bronchiolitis when this was filmed.
Her anxious mum can be heard saying “I’m not happy with that” in the video, recorded at home as she was on the phone to NHS 111.
Bronchiolitis is a viral infection with mild cold-like symptoms in adults and older children but more serious in young babies.
It is caused by respiratory syncytial virus (RSV) – a common germ spread through tiny droplets from coughs and sneezes, or by touching someone infected by the virus, or something contaminated by the virus like a toy.
O’Brien, a presenter, podcaster and blogger, wrote in a Facebook post which has been shared more than 27,000 times: “We’re heading into the dreaded season of non-stop colds coughs and viruses so thought it was worth a mention.
“When Luna was four-weeks old she had a really quiet day of sleeping and barely any crying.

“I was watching her sleep next to me and realised it didn’t look right. I unbuttoned her babygrow and this is what I saw.
“Sucking in at ribs is a sign to get your baby or child to hospital.
“She had bronchiolitis and her oxygen levels were very low. Luckily after a night on oxygen, she made a very good recovery.”
The advice given by O’Brien is backed up by former nurse, health visitor and author Sarah Beeson.

“If you see that ‘sucking in’, if you see that difference with breathing, I absolutely agree to seek medical advice. Don’t hang back – you’re not bothering the doctor. It’s their job to look at your baby.
“Mothers should trust themselves. Who knows the baby better than his mother? It’s your right to get a medical opinion.”
Beeson, whose book is called Happy Baby, Happy Family, said worried parents should count up the symptoms they identify in their child – from being off their feeds and not urinating to a noisy or wheezy breathing with a “red light” for a temperature or the sucking in movement.

“It’s lovely to know (this mother) did all the right things. She thought it wasn’t right and went to hospital.”
O’Brien has been praised for sharing the video on her Facebook page.
One response said: “I’ve heard this but never knew what to look for. Really helpful to see it, thank you.”
WASHINGTON (AP) — The U.S. population is projected to grow by 15 million people in 30 years, a smaller estimate than in previous years, due to President Donald Trump's hard-line immigration policies and an expected lower fertility rate, the Congressional Budget Office said Wednesday.
The nonpartisan budget office projected that the U.S. population will grow from 349 million people this year to 364 million people in 30 years, a 2.2% smaller gain than it had predicted in 2025. In September, the office issued a revised demographics report that showed Trump’s plans for mass deportations and other strict immigration measures would result in roughly 320,000 people removed from the United States over the next 10 years.
The country's total population is projected to stop growing in 2056 and remain roughly the same size as in the previous year, the CBO said. But without immigration, the population would begin to shrink in 2030 as deaths start to exceed births, making immigrants an increasingly important source of population growth, according to the report.
Even if the limits on immigration and increased deportations end with the Trump administration in three years, “it’s still a demographic shock,” said William Frey, a demographer at the centrist Brookings Institution.
Social Security and Medicare, which are already buckling under an aging population, will be under increasing pressure with even fewer than expected people in the labor force paying taxes. By the end of the decade, all of the nation’s baby boomers, born between 1946 and 1964, will be over age 65.
With fewer immigrants in the labor force and projections for U.S. fertility rates showing a long-term decline below replacement levels, “that reduces the number of kids who are going to be born in that four-year period” of the second Trump administration, Frey said.
The latest numbers come as Trump has pushed for the largest mass deportation campaign in history. The CBO's numbers account for the success of those efforts in the first year of his second term in office.
The administration has used a variety of methods to remove people from the country, including a visa ban on applications for immigrants from some countries and deploying Immigration and Customs Enforcement agents in U.S. cities to track down immigrants who are in the country illegally.
Trump’s tax and spending law, passed by Congress and signed in July, included roughly $150 billion to ramp up his deportation agenda over the next four years. This includes money for extending the U.S.-Mexico border wall, building detention centers and adding thousands of law enforcement staff.
When it comes to estimating the nation’s population and future growth, immigration is always the wild card because it varies much more year to year than the number of births and deaths. Immigration has fueled U.S. population growth this decade because of an aging population and fertility lower than the replacement rate. For a generation to replace itself in the absence of immigration, the fertility rate needs to be 2.1 births per woman. But it was expected to be 1.58 in 2026 and is projected to drop to 1.53 in 2036 where it will remain over the next two decades.
The U.S. Census Bureau said that immigration increased by 2.8 million people in 2024 over the previous year.
Since Trump returned to office in January 2025, though, demographers and economists have struggled to decipher the impact of his policies on immigrant growth in the United States.
The bureau’s population estimates for last year have not been released yet, but the Current Population Survey estimated that the number of adult immigrants fell by 1.8 million people from January to November 2025. But those numbers have come under scrutiny, with some experts claiming they may reflect a decline in participation by immigrants in the survey rather than a dramatic drop in immigrant numbers.
Last September, the CBO reduced its immigration estimate for 2025 by 1.6 million people, and it said Wednesday that the U.S. added 410,000 immigrants last year. Immigration is projected to gradually increase through 2030, and then grow more slowly through 2036 because of fewer international students and temporary workers, before jumping up to an average of 1.2 million people a year from 2037 to 2056, the CBO said.
“These immigrants bring both themselves and the potential for children in the near term,” Kenneth Johnson, a senior demographer at the University of New Hampshire, said in an email. “They contribute both to the labor force through their arrival but also to the potential future growth of the US population through their potential to have children in the near term.”
