Six stages, like the pencil marks on a doorframe. Each will get its own page: what’s typical, what varies enormously, and what’s worth reassessing in six months — always with the sources in plain sight.
stages are maps, not territories — every child travels them their own way, and so does yours
Each cell takes you to the library already filtered by that age. The full stage guides — written with cited evidence from serious institutions and put through editorial review — arrive with launch and in the weeks that follow.
The traits serious research describes for the stage — cited and linked, never hearsay.
The most important section: the huge ranges of normal, to defuse comparison and panic.
Activities from the library for today, and the questions worth asking yourself again six months from now.
