Parents raising bilingual kids: what's actually worked for keeping the mother tongue alive?

Building Pitara Stories with bilingual reading as a core feature has taught us something interesting: once kids start school, the dominant language takes over and it gets harder to keep the mother tongue alive at home. This is a universal challenge but solutions vary wildly.

Curious to hear from this community: if you're raising bilingual kids, what's actually worked for you? Books, video calls with grandparents, weekend immersion, apps, songs? What stuck and what didn't?

We've now shipped side-by-side bilingual reading in 7 languages and we're trying to understand if there are use cases we haven't thought of. Adult learners, family bonding, language preservation across generations, cultural connection through stories. Interested to hear how this challenge shows up in different families.
