How to keep your home language alive when daycare starts

17 October 2026 · 7 minute read

Expect the switch, and plan for it. Once daycare or school starts, the community language gets most of your child's waking hours and all of their friends, so the home language needs its own time, its own people and its own reasons to exist.

Lots of parents notice it within months: a kid who chatted happily in Portuguese starts answering in German, or comes home with English songs and quietly drops the Spanish ones. It's common, and very fixable, especially in the toddler and preschool years.

Why the community language takes over

It's mostly arithmetic. Nine hours a day in one language beats two in another, and the language of other kids carries extra weight because it's the language of play. In De Houwer's survey of 1,899 families in Flanders, every child spoke the community language, while far fewer spoke the language their parents brought from elsewhere. The kids most likely to keep it were the ones whose parents both used it at home, which Grosjean's summary of the study puts at close to all of them.

The slide is slow, which makes it easy to miss. A study that followed 147 children of Spanish-speaking families in Florida from age 3½ to 12 found that the share of Spanish they heard at home fell from about two thirds to about half, and their English vocabulary grew far faster than their Spanish. Children who heard more Spanish early kept growing faster in Spanish, and the authors' conclusion is right there in their title, early experience is not enough: the home language kept depending on home exposure all the way to age 12 (Johnson and Hoff, 2026).

If you worry that protecting the home language will hold back the local one, a review of 42 studies found no case where more heritage-language exposure hindered children's majority language (Hollebeke and colleagues, 2020).

If both of you speak the home language, the strongest single move is making it the language of the house and trusting daycare with the rest. If only one of you does, that parent's time gets precious, and the other parent can still help by learning songs, playing along and never treating it like a secret language.

Watch what big brothers and sisters bring home

Older siblings are the other quiet force. In families where a school-aged sibling went to an English-only school, that sibling spoke mostly English to the toddler, the mother used more English too, and the toddlers ended up relatively stronger in English and weaker in Spanish than toddlers without school-aged siblings, with the same total vocabulary across both languages (Bridges and Hoff, 2014). A major review of heritage-language research cautions against nudging siblings to speak the community language at home to help the little one, since the community language gets plenty of practice elsewhere (Paradis, 2023).

Nobody wants to police sibling chatter, so give the big kid a job in the home language instead: reading to the little one, leading the bedtime song, being the one who knows the game in Italian.

Give the language its own moments

Routines work because they don't run on willpower. Pick a few moments that always happen in the home language and protect them: the bedtime story, the bath song, Saturday breakfast, the walk to the playground. Kids come to expect the language there, and it starts to feel like part of the moment.

Books matter more than most parents expect, because picture books use words that never come up in daily conversation. Borrow or swap them with other families in your language, and read the same favorites over and over, which is what toddlers want anyway.

Reading in the home language doesn't cost the school language either. In a study of 33 preschoolers from Hmong and Spanish speaking families, storybook reading at home in the home language was at least as effective for learning English words as storybook reading at home in English (Roberts, 2008).

Give your child a reason to use it

Kids speak the languages they need, and speaking a language is part of how they get better at it. A study that followed 47 bilingual children from 2½ to 3½ found that the children who used English more grew faster in speaking it, even after counting how much English they heard, while understanding grew about the same (Ribot, Hoff and Burridge, 2017). A child who understands your language but never has to answer in it can end up understanding a lot and saying little.

A grandparent who only speaks the home language is the best teacher you've got, and regular video calls count: the American Academy of Pediatrics treats live video chatting with family differently from other screen use, even for babies. The lab work agrees. Toddlers of 2 to 2½ learned new verbs over Skype about as well as from a person in the room, and nothing from a recording of the same kind of lesson (Roseberry, Hirsh-Pasek and Golinkoff, 2013), and children of 12 to 25 months who had FaceTime chats recognized their partner a week later and learned from them, while children shown recorded videos didn't (Myers and colleagues, 2017). Playgroups, other families from your community and trips to places where the language is everywhere all make it real.

When your child answers in the community language, keep going in yours. Show you understood and reply in the home language, or repeat what they said back in it, without making it a rule or a punishment. Many families find that staying relaxed and consistent beats insisting.

Use screens the way you'd use a book

Screens can help a little, mostly when a grown-up is in on it. The World Health Organization recommends no sedentary screen time for children under two and no more than an hour a day for two to four year olds, and the AAP stresses watching and playing together.

The gap between a person and a recording is large for the youngest children. Nine-month-olds who spent about five hours over four weeks with a live Mandarin speaker learned to hear Mandarin sounds, while babies who got the same Mandarin from video or audio recordings showed no learning at all (Kuhl, Tsao and Liu, 2003). A meta-analysis of 59 reports puts the average learning gap between video and face-to-face teaching at about half a standard deviation for children up to six, shrinking as they get older (Strouse and Samson, 2020). Sitting with them changes the picture: toddlers whose parent joined in alongside a video learned the new word, and toddlers watching on their own didn't (Strouse and colleagues, 2018).

That's the idea behind LingoPlaytime. The games are short, they speak your home language in a natural-sounding voice and say your child's name, and they're meant to be played together: you tap, you both say the word, you point at the real thing in the room. Goodnight room even ends on its own, so the last game of the day leads into bed instead of another round. More on this in what toddlers actually learn from screens.

And if your child is mixing languages or seems slow to talk in the meantime, here's what the research says about bilingual toddlers and late talking.
