I totally have to agree with Pattie. I love that book and I also really like the book "Better Late than Early" which is really marketed towards homeschoolers but it is an excellent read. There is good research that talks about how interaction with a real adult is so much more meaningful and significant than electronic learning toys. (Remember the big broo-ha-ha over the "Baby Einstein" videos making your kids dumb?) That is part of it. (

Although I gotta admit my kids have love those fridge things from Leap Frog.)
There is also very compelling research on how when kids are just exposed to a variety of experiences as opposed to 'book and desk' learning it enables their reading comprehension ten fold. . .in other words, if you want to improve their reading. . .teach them letters and stuff later rather than earlier. There have also been a couple of studies suggesting that teaching writing too early actually leads to later problems like carpel tunnel bc their little bones just aren't ready yet. I could probably write a whole book on this subject but really, you don't need to be doing anything out of the ordinary with your daughter right now. Just enjoy her--don't be so anxious for her to grow up.
We do art stuff, music and lots of reading out loud of all types of books. . .not just "baby books". (We are currently into Beatrix Potter.) We play games, go to the park, the zoo and in the summer we garden. Learning should be fun at this age and remember, first impressions are everything. You are setting her up for a lifetime of learning and inquiry and honestly, I think just giving them things stifles their creativity and natural curiosity. I think following your child's cues are key as well. I certainly wouldn't discourage one of my kids from reading if they wanted to and pursued it on their own.
FWIW, preschool is totally optional at our house. . .if the kids don't want to do school they don't have to. (I mean the preschoolers before age 6. . .once they turn 6 I'm required by law to follow curriculum.) Television however is almost always off with rare exception. My older three children are several grade levels ahead in several subjects. . .one of those children has been "recognized" as highly gifted. . .and all this from playing, reading and exploring.
I'm sorry I've written a book. If you want more info let me know. . .
