There's a much better way to talk to babies than baby talk

It turns out, a lot gets lost in translation when you talk to a baby in baby talk. A new study from the University of Washington found that babies who are spoken "parentese" have better language development than babies who are spoken to in "baby talk." The study was published in the Proceedings of the National Academy of Sciences.

Baby talk tends to consist of simplified grammar and exaggerated sounds. "What people think of as baby talk is a combination of silly sounds and words, sometimes with incorrect grammar," Naja Ferjan Ramirez an assistant professor at the department of linguistics at the University of Washington told CNN, "like 'Oooh, your shozie wozies on your widdle feets."

Parentese, on the other hand, consists of adults using real worlds in a more baby-friendly cadence. The term has been around since the mid-1980s, and a lot of parents tend to do it naturally. "Parentese has three characteristics," Patricia Kuhl, the co-director of the Institute for Learning & Brain Sciences at the University of Washington, told CNN. "One of them is that it has a higher overall pitch, about an octave higher. Another is that intonation contours are very curvy; the highs are higher, the lows are lower, and it sounds excited and happy. And then it's slower, with pauses between phrases to give the baby time to participate in this social interaction."

Researchers at the University of Washington studied 48 families. All of the families naturally spoke some parentese to their children, however researchers coached half of the parents on how to speak proper parentese. The parents came into the lab for coaching when their babies were 6, 10, and 14-months old.

The children who were spoken to in parentese had a 100-word vocabulary by the time they were 18-months-old. In comparison, the babies that weren't spoken to by parents coached by scientists had a 60-word vocabulary. "Children of coached parents produced real words, such as ball or milk, at almost twice the rate of children whose parents were in the control group," Ferjan Ramirez told CNN.

The parents were also encouraged to talk to their babies in back-and-forth conversational exchanges. According to researchers, more turn-taking correlated with babies who had better language development. It turns out, one of the most important part of parentese might be that it engages babies and encourages to respond, even if they're still only fluent in baby talk. "Babies need to be engaged socially in order to learn language. They have to have a drive to communicate. They have to want to, and parentese seems to help make them want to," Kuhl told CNN.

It just goes to show, even infants don't like to be infantilized.

Temwa Mzumara knows firsthand what it feels like to watch helplessly as a loved one fights to stay alive. In fact, experiencing that level of fear and vulnerability is what inspired her to become a nurse anesthetist. She wanted to be involved in the process of not only keeping critically ill people alive, but offering them peace in the midst of the unknown.

"I want to, in the minutes before taking the patient into surgery, develop a trusting and therapeutic relationship and help instill hope," said Mzumara. Especially now, with Covid restrictions, loved ones are unable to be at the side of a patient heading to surgery which makes the ability to understand and quiet her patients' fears such an important part of what she does.

As millions of Americans have raced to receive the COVID-19 vaccine, millions of others have held back. Vaccine hesitancy is nothing new, of course, especially with new vaccines, but the information people use to weigh their decisions matters greatly. When choices based on flat-out wrong information can literally kill people, it's vital that we fight disinformation every which way we can.

Researchers at the Center for Countering Digital Hate, a not-for-profit non-governmental organization dedicated to disrupting online hate and misinformation, and the group Anti-Vax Watch performed an analysis of social media posts that included false claims about the COVID-19 vaccines between February 1 and March 16, 2021. Of the disinformation content posted or shared more than 800,000 times, nearly two-thirds could be traced back to just 12 individuals. On Facebook alone, 73% of the false vaccine claims originated from those 12 people.

Dubbed the "Disinformation Dozen," these 12 anti-vaxxers have an outsized influence on social media. According to the CCDH, anti-vaccine accounts have a reach of more than 59 million people. And most of them have been spreading disinformation with impunity.

The global eradication of smallpox in 1980 is one of international public health's greatest successes. But in 1966, seven years after the World Health Organization announced a plan to rid the world of the disease, smallpox was still widespread. The culprits? A lack of funds, personnel and vaccine supply.

Meanwhile, outbreaks across South America, Africa, and Asia continued, as the highly contagious virus continued to kill three out of every 10 people who caught it, while leaving many survivors disfigured. It took a renewed commitment of resources from wealthy nations to fulfill the promise made in 1959.

Forty-one years later, although we face a different virus, the potential for vast destruction is just as great, and the challenges of funding, personnel and supply are still with us, along with last-mile distribution. Today, while 30% of the U.S. population is fully vaccinated, with numbers rising every day, there is an overwhelming gap between wealthy countries and the rest of the world. It's becoming evident that the impact on the countries getting left behind will eventually boomerang back to affect us all.

The international nonprofit CARE recently released a policy paper that lays out the case for U.S. investment in a worldwide vaccination campaign. Founded 75 years ago, CARE works in over 100 countries and reaches more than 90 million people around the world through multiple humanitarian aid programs. Of note is the organization's worldwide reputation for its unshakeable commitment to the dignity of people; they're known for working hand-in-hand with communities and hold themselves to a high standard of accountability.

"As we enter into our second year of living with COVID-19, it has become painfully clear that the safety of any person depends on the global community's ability to protect every person," says Michelle Nunn, CARE USA's president and CEO. "While wealthy nations have begun inoculating their populations, new devastatingly lethal variants of the virus continue to emerge in countries like India, South Africa and Brazil. If vaccinations don't effectively reach lower-income countries now, the long-term impact of COVID-19 will be catastrophic."
