The same awkward advice was given to immigrant parents sitting in pediatricians’ waiting rooms across America for decades: speak English at home. The argument, presented with clinical assurance, was that exposing a child to two languages simultaneously would cause them to become confused, delay their speech, and regress academically. Quietly, parents who brought their native tongue from abroad were instructed to leave it at the door. Many of them paid attention. A few of them still feel bad about it.
Now, without much fanfare, that advice is being walked back. The medical community, especially pediatricians who work closely with multilingual immigrant families, has changed its stance in ways that would have seemed improbable twenty years ago, and the research on which it was based has not held up. Researchers at Florida International University and other pediatricians have come to the conclusion that medical professionals should actively promote bilingualism rather than discourage it, citing a variety of cognitive, social, and financial advantages that build up throughout a child’s development.
As of right now, the science underlying this reversal is quite sound. Research has repeatedly shown that children who are raised speaking two languages do not experience higher rates of language disorders than their peers who are monolingual. It turns out that code-mixing, which used to worry both parents and clinicians when a child blended languages in the middle of a sentence, is a normal and even sophisticated aspect of bilingual development rather than a sign of confusion. “I want agua” is not a sign of difficulty. They are using both systems simultaneously, just as bilingual brains do.
The way this change interacts with the current political environment is what makes it intriguing. Pediatricians in Nashville, San Francisco, New York, and other cities started having completely different conversations with immigrant families in the spring of 2025. These conversations covered guardianship plans, family separation, and what happens to a child’s medical care when a parent is detained without warning, in addition to language. Although it is rarely discussed, that crisis has a bilingual component. Children whose emotional and cognitive development is being shaped by factors far beyond any language strategy include a 10-year-old who asks his mother every morning if they will see each other again and a toddler who refuses to eat after his father was caught in an ICE raid. Telling those same families to stop using their native tongue at home a generation ago is difficult to avoid thinking about.
Compared to the previous guidelines, the practical advice coming from pediatric researchers and speech-language pathologists is more sophisticated and likely more helpful. There is no one right way to raise a bilingual child; some families find success with one parent speaking only one language, others find success with speaking a minority language at home, and still others find success with mixing freely. Experts in the field say that exposure and consistency are important. Youngsters take in everything around them. Even though it doesn’t feel like formal instruction, things like a grandmother speaking Urdu on a video call, a Sunday routine done entirely in Spanish, or a car ride filled with Mandarin music add up.
It seems that much of the previous concern about bilingualism was more about cultural assimilation disguised as clinical language than it was about child development. Although linguistics did not support the idea that English had to supplant all other languages, it did fit neatly into a larger American narrative about what immigrant families were expected to become. Despite being trained scientists, pediatricians work in a cultural setting. They might have unknowingly absorbed the presumptions of that culture.
The current reversal is worth keeping an eye on, not only as a parenting tale but also as a tiny sign of how institutional guidance shifts when the evidence eventually shifts in the opposite direction. It’s too late for the families who were told to stop to regain those years. The door is open for everyone else.
