It turns out that the mother is using her daughter's fairytale video to raise money for a charity in Mongolia.
Her mother speaks perfect English (and can translate between the 2 languages) and I'm wondering why she never taught it to her daughter who seems to be very smart, adorable, funny, curious, animated, expressive, etc.. (I guess why she's so popular on the internet). I am sure she'd pick up a new language easily.
The quality of videos on Vimeo seem better (both in terms of content and video file quality) but the downside is that (for me at least) they seem to take longer to load than those on YouTube.. but also there are far fewer videos on there..
Here's a blog with a bit of a description about Capucine's video:
Here, the Vimeo staff made Capucine a Happy 5th Birthday video
and here, her mother filmed her reaction to it (had to translate it for her)
Capucine is très très adorable! And it's amazing how much vocab and grammar I can learn from watching her fairytale video!
