We speak Russian at home, and it gets reinforced at the grandparents home, so we watch them all in Russian.I like this comment with one caveat: Why use dubbed Russian youtube videos?
Babies will pick up the Russian on their own or at least become comfortable with the pronunciation. Practice some basic phrases such as time to eat, sleep, wake up, etc. and pretty soon you'll have a Putin oligarch after 2 years!
Other cartoons I recommend from the east include "Kolobok" (English dubbing is pretty good, I enjoy it along with the Russian version) and "Zhiharka". Get with subtitles and read aloud so the tyke can pick it up. Bolek i Lolek is also great. And don't forget Wolf and Rabbit!!!
Practice Russian! You'll be singing along in no time!
But it’s good to see that there English dubbed ones. Of course up to a certain age the child cares little for what language it’s in.
