DEVELOPMENTAL MILESTONES · YEAR TWO

15, 18, 24 months per the CDC checklists (2022 revision): 41 milestones that at least 75% of children reach by each age

Built as a memo rather than a table: the thing worth hanging it up for reads across the room, with the full reference in smaller type below it.

Three sizes in one archive — from a sheet on the fridge to a poster on the wall.

Formats: A4 · A3 · A2
What you get: Print-ready PDFs, one per size, with every letterform converted to outlines — nothing to install, nothing to shift.
Subject: body and care · everyone · reference · nursery

The items are verbatim from the CDC “Learn the Signs. Act Early.” checklists, 2022 revision (Zubler et al., Pediatrics). The coloured dot marks the developmental domain — see the legend at the top. This is a surveillance tool, not a diagnosis: if a milestone is missing, talk to the pediatrician rather than wait. The AAP recommends general developmental screening at 9, 18 and 24 months. Checked 2026-08-13.

WALKING MOVED TO 15 MONTHS

The 2022 revision moved independent walking from 12 to 15 months: only about half of twelve-month-olds can do it, and a milestone is now what at least 75% of children reach by that age.

That is why walking appears on these sheets as a three-step ladder: along the furniture at 12 months, first steps of their own at 15, walking with no support at all at 18. A child who is not walking on their first birthday is right on schedule.

Colour carries meaning, but meaning never rests on colour alone — the sheet reads in black and white.
Nothing about how it was made: the sheet carries only what the reader needs.

Printing

Three sizes in the archive: A4 — 210×297 mm, A3 — 297×420 mm, A2 — 420×594 mm.
All text is converted to outlines. No fonts to install, and nothing shifts on another machine.
White background and sparing fills — it prints on a home printer without draining the cartridge.
Margins of at least 10 mm: a home printer cannot print to the edge.
No stroke thinner than 0.3 mm, so nothing disappears in print.

Why the numbers can be trusted. Every countable number here is computed from data rather than typed in, and the sheet must pass 9 independent checks before it is allowed to build — how many items there are, the order they come in, and the claim in the highlighted box itself. If one fails, there is no file.
