One thing I've noticed is that Highly gifted or PG kids really don't need these "programs" in toddlerhood.
OK, I'd better duck before a stone hits me.
LOL I won't be throwing the stone. I agree 100%
My kids aren't PG (possibly HG - I am HG and they are very similar).
Anyway, DD(now 9) coerced me into helping her learn to read when she was a toddler. She too, had the alphabet mastered at 16 months and didn't talk until 24 months (raging perfectionism, lol). She was driven, driven, DRIVEN to learn what these "things" were in books - she'd crawl after me, furniture walk after me, book in one hand... lol I'd try and hide (seriously - she was so non-stop). She point to something in the book and stare into my eyes, until I gave her a label for it. She was eerily quiet, but SO intense - she'd look INTO you, not at you.
Anyway. I had heard of these toddler programs and they kind of baffled me. "Why would anyone need that?"
A friend of mine with a "typical" son close in age once said to me "hey can you teach my son to read?" (DD and her son were about 3 at the time). I didn't know how to tell her that it wasn't ME who taught my daughter to read without offending her son's cognitive ability (which is perfectly fine and "normal"). I managed to steer the conversation on to something else...
