Well, to some kids, academics IS play, so don't feel quilty for following your child's/children't lead. I think there is this social stigma attatched to kids that LOVE to learn. That their parents are "pushing" them. That used to prevent me from providing them a lot of opportunities they would have enjoyed.
Now I just don't worry about it, I do what they want to do.
DD5 is happily completing a library reference workbook when we go to the library every week. Just one page each time. She's really enjoying herself. I saw another mom I know from the public school and she approached us and said: "Oh, you're already preparing them for next year?"
I told her, no, DD5 doesn't need to know any of this stuff for first grade. She just really thinks its fun and wants to be able to navigate the library system without my help.
She actually looked mad when she walked away.
shrug.
