For me, the second video was different but it kept repeating, so after 6 tries I quit. Also, it's impossible to navigate back to a sequence of the video, so I couldn't train to see when the child started to go wrong. There's also no link to Youtube. And finally on the iPad the background is black and the video is black and doesn't start, so I really wondered what the website was about at the beginning. Typical example of how doing less design and not removing Youtube's default controls would have helped. The rest of the website is a great idea implemented with talent, despite the details I teport.
