Thanks for the additional details, Hoosier. I'd say she definitely sounds G, but what flavor of G is hard to say. The memory for songs, books, sight words etc. stands out to me, along with her vocabulary and interest in reading. Keep on letting her lead the way and I'm sure she'll continue to amaze you!

I've got three early walkers (7 months, 8 months, and ten months) and one late walker (15 months). All were fluent readers by age three at the latest. The most precocious of my readers was reading signs at 12 months, had many sight words at 16 months, and we discovered that he could read virtually anything in clear print just after he turned two. At that age, he loved to read adult field guides to identify things form his rock and seashell collections. He is not my strongest reader now though, as his little sister has surpassed him. She is much more of a bookworm and is very, very fast! The test admin who did her evaluation said that she scored higher than any other child she's ever seen on some reading subtests. She was past grad school level at six years old. It's been fun watching my kids play developmental leapfrog with each other. Skills don't always develop along a predictable path, and I have given up trying to guess where they will be in any particular area in a year, two years, or more.

My kids were all pretty verbal early on, and I think I am a bit out of touch with what is typical. Let me see if I can find a chart: http://parentcenter.babycenter.com/0_milestone-chart-25-to-30-months_1496593.pc

That's not the one I wanted... let me see:

That's the one! Maybe you'll find this helpful.

take care-
