> In the first months of her life, I kept a spreadsheet of my daughter’s milestones.
I’d love to see some spreadsheets to read other parents’ column headers beyond weight, height, head size.

My son was slow to smile, and very slow to walk. But he was evaluated with a 160 IQ at age 4. I have a friend who didn't talk until he was 5 years old. His parents were afraid he was developmentally delayed. In fact, he went to Berkeley for undergrad and Stanford for his PhD and you never would have guessed he didn't talk until he was 5.
So development speed is extremely wide standard deviation to the point where data from the first several years is fun if you want to brag but useless for the purpose of generating any useful data on whole, except for the severely delayed.
