Remember second language acquisition takes time

Remember second language acquisition takes time. You will not see results right away, but by having your child listening and practicing a foreign language at least once a week, you are extending their critical period for learning a second language, and most importantly they are acquiring the ability to speak the language without or almost no foreign accent . Older learners would not reach this native-like speaking level.

“The Critical Period Hypothesis states that the first few years of life is the crucial time in which an individual can acquire a first language. If language input doesn't occur until after this time, the individual will never achieve a full command of language.”
