That's fascinating, and terribly cute. I'm determined to get my daughter to understand the equal volumes thing before that age. :)

What I wonder is if they can be taught the difference, and then apply it at that age. It must be difficult to discern genuine developmental stages from average learning achievements.

That's a long debate, if you can even teach that stuff. One side wil say: the kids just can't understand it. They haven't reached that stage in their development yet; others will say: the child is just lacking information: if you do it right, she'll get it.

Let us know how that goes. ;)

The flashcard game seems really great. Now I, too, am wondering how long it'll take!

Science is fun.

edit: Oh, oh! You know what you should do? You should keep a list of the first fifty words she speaks. The first fifty are easy to notice, because she is learning slowly in this first period: she's still trying to control the musculaure of her mouth while attaching meaning to the sounds. But after a while, about the second year, it becomes more complicated: I think she is going to learn about a word per hour.
