My son who is 3 and non-verbal has been doing this for a while. He likes to watch his favorite shows in other languages and songs and some random shows I never even heard of. Haha! I don't know that he understands what they are saying, but he does laugh at the funny parts! 😊

My son also watches cartoons on YouTube in other languages French Spanish no idea why tried to explain but he gets very angry wants it that way
He also watches PBS sponsors over and over on ipad

My 6 yo is fixated on the Russian alphabet and the chart of animals who's names begin with each letter. He wants me to write the letters too, so I have been learning them. My mother thinks this will interfere with his progress with regards to English. I'm a big advocate of nurturing his interests. The variety of sounds he's learning seems to be helping him with his speech.

My son loves to watch things in Russian and Mandarin.... He even sings the songs, I'm not sure if he understands!

my son is 3 almost 4yr old, he does that too, watching videos or playing some apps in other languages.
