Prioritize it
Making this a priority goes hand in hand with being proactive. If the development of your child’s minority language isn’t one of your family’s highest priorities, chances are the majority language will quickly come to be dominant and the minority language will be relegated to a more passive role. Don’t underestimate how quickly this can happen once the child enters the world and spends the bulk of his hours bathed in the language of the wider community. Make the minority language a priority from the get-go and you’ll strengthen the odds of achieving long-term success.
