Some kids have problems. Please don't make blanket statements.
I am a stay at home mom, and my daughters had severe speech problems. One didn't talk until she was 5 1/2.
My son didn't read until he was in first grade. He just wasn't ready. He's been tested, and he has an IQ of 130 (gifted).
Some kids are quick learners and some kids aren't, and it has nothing to do with how much time is spent with the kid. I spent hours on reading, colors, etc with my daughters. They went to speech twice a week since they were two. They went to preschool 2 mornings a week.
I'm sorry my post seems to have hit a nerve with you.
I'm not really sure what part of my post you take exception to, however. Did you feel that your children needed pre-K despite the one-on-one time you spent with them? Or did you think I was saying that all children would be as advanced as the ones in my family, if enough time was spent with them?
The children in my family are like those in mythical Lake Wobegon - they're all above average. ;-)
