Milestone Books by Age: What to Capture, and When

1. 1
   0–12 months: the first year

   Hospital day, going-home outfit, month-by-month growth, first foods, first holidays, the people who held them first.
2. 2
   12–24 months: first words and faces

   The words they actually say, the family members they can name, favorite objects, the walk-to-the-park route.
3. 3
   2–4 years: all about me

   Their room, their comfort object, best friend, favorite meal, what they say they want to be. Their own answers, quoted verbatim.
4. 4
   3–5 years: starting school

   The building, the teacher, the cubby, the drop-off routine, the classroom friends — read before day one to lower nerves.

• ✓Their exact mispronunciations — write them the way the child says them.
• ✓Ordinary rooms: the nursery corner, the kitchen chair, the car seat view.
• ✓Caregivers outside the family — the daycare teacher, the neighbor, the sitter.
• ✓Hands and feet at scale, next to a familiar object.
• ✓The pet, the stroller, the stained lovey. These date a year better than posed portraits.

A milestone album lives on a shelf and gets opened twice a year. A milestone board book lives in the toy bin and gets opened weekly by the child it is about — which is how children build autobiographical memory. Because pages expand from 20 to 56, a busy year does not have to be trimmed down to fit.
