exactly this. my youngest daughter would watch all her movies in french, with the english subs.
she caught on to a few words, phrases. so, i taught her to count to 10 in french. it was pretty cool for a
kindergartner.
but since i don't speak kannada, i'll have to find him some spanish, or french, or even german youtubes for kids.
also, i don't think it's fair the my 4 year old can pick up kannada where here i was thinking he was watching some russian video (sounds like russian a little)
^ i am completely joking about that last bit
