Its much easier for children to pick up a second language then adults. However, adults retain more what they have learned if they discontinue using it.
Just a couple of thoughts. I have no idea how you learned to read when you were two, Scott. My daughter just turned two and she can bairly talk. She can say, top off, and there he is, and I love you . . . sort of. . . but she is far from understanding many words much less reading them off a page. You must be some sort of genius.
Anyway, this is a funny conversation, because usually the reverse is being argued. Usually the MVs complain that the KJV is too hard to understand and the KJV counter with the fact that there two and a half year olds are reading it. I don't think 2 and 1/2 year olds are reading much of anything, but I must run in the dumb circles.
When I was six I had graduated to See spot run, and jack and jill go up a hill and best of all, "Ann likes red", so it is doubtfull I was following along in any version, but once again, I don't seem to be the brightest one on this board.
