Teaching Your Kids Your Mother Tongues
I learned early, to have your child speak the mother tongues of each parent, have each parent exclusively speak to the child in their mother tongue.
Speaking to your child in one language while the other parent speak in another language will boost your child’s ability to learn more than one language.
This will create a direct association for your child with the person and the language spoken to them.
For me, my sons associate English with me and Japanese with my wife. I can speak to my kids in English, get an English response and the same result when my wife speaks to them in Japanese.
More impressive is when I ask my kids to tell my wife something, they would translate directly from one language to another naturally.
