We just took it as it came until he hit school age. I had lots of books and puzzles and toys around, just like most people here.
I did try to have above grade level stuff on hand, but as it turned out, not as far above grade level as I probably should have had. (I thought he was MG. Doh!

My whole frame of GT reference was skewed, I'm afraid. I didn't realize that until he was tested.) I also probably should have done more with math with him. But DS is an introvert, so if he didn't push, I didn't follow. I do wish I'd been a bit more aware earlier.
Woulda, coulda, shoulda, right? He seems to be turning out okay, so I'm not kicking myself as hard as I once was!

But anyway, I wouldn't worry about doing anything formal unless you are like BWBShari and have no choice in the matter. Follow your child's lead and have lots of above-age level materials on hand for if/when you need them.
And then hang on! It's a wild ride!
