We keep a strict home-language-only rule at the dinner table. Imperfectly followed most nights, but it’s clearly better than nothing over time.
Our kids are picking up the local language fast at school, which is wonderful, but they're already answering us in it at home and losing words in our mother tongue. Keeping the home language going takes real discipline. Did you push it, and did your kids thank you later — or resent it at the time?
