How much German does my child actually need?
Nearly every family abroad reaches the same question: is what we’re doing enough? And nearly every family hears the same number — about 30 percent.
Where the number comes from
Bilingualism research often cites a range of roughly 20 to 30 percent of waking hours as the point where children typically don’t just understand a language but actively speak it. Treat that as what it is: a rule of thumb, not a law of nature. Children differ, situations differ, and no single percentage can capture all of it.
It’s still useful — not as a target to tick off, but as rough orientation. It makes one thing clear: this isn’t about perfection, but it also isn’t about twenty minutes of Sunday reading.
Do the maths honestly, once
Take a normal week. A daycare-age child is awake roughly 70 to 80 hours. Then subtract:
- daycare or school: often 30 to 40 hours of community language
- playdates, clubs, neighbours’ children
- family time where everyone switches to the shared language
What’s left is honestly often less than it feels. Plenty of families who consider themselves “pretty consistent” land at 15 to 20 percent. That’s not a failure — it’s a starting point.
Quality beats raw volume
Not every hour counts equally. What makes the difference:
- Dialogue, not background noise. An audiobook playing is input, but language grows in the back-and-forth. Ten minutes of real conversation beats an hour of ambient German.
- More than one person. Children who only ever hear German from one parent often file it as “Mum’s language.” Video calls with Oma, German friends, visitors — all of it makes German a language that several people speak.
- Recurring situations. The same words in the same context, over and over — getting dressed, setting the table, bath time. That’s how vocabulary sticks.
What this means in practice
Going from 15 to 30 percent sounds like doubling your effort. Usually it isn’t. It comes from a few reliable moments that used to be bilingual or English: the walk to daycare, dinner, the bedtime ritual.
Twenty extra German minutes a day is more than two hours across a week. That shifts the share noticeably — without anyone rebuilding their life.
And because nobody can estimate this honestly without counting, Wortbeet has a meter for exactly that: a running estimate of your share, with one concrete suggestion when it slips. How to choose the moments is in Ten German rituals for everyday life.
