My 2-year old Noah loves watching Dora and Diego. He learned really well from watching that show. We still have to work on numbers 6-10 though, but it's a pretty good start for him to learn the Spanish language. I won't be surprised if he'd be speaking in Chinese one of these days because he watches Ni Hao Kai Lan also with much fondness. :)
Did he say "engkow! for cinco? ahehe :)"
