Wow, that's amazing! I don't understand how people can argue against teaching babies sign language after seeing something like this. Very impressive.
I think that this particular baby is actually deaf or hard-of-hearing and that is why they've taught her BSL. But just seeing this shows how much a baby can learn in just 2 years and how much more of a conversation a baby can hold at that age. :)
