Baby Milestones Chart 0–12 Months (Free Printable)

By Tiny Moments · November 2026 · 6-minute read

Every parent ends up asking the same quiet question: is my baby doing what babies do at this age? This chart answers it the way pediatricians do — with the CDC checkpoints at 2, 4, 6, 9 and 12 months — and it treats milestones the way they deserve to be treated: as moments to notice and keep, not tests to pass.

The milestones chart: 0–12 months

Read the chart by checkpoints, not by exact birthdays. A baby who does something at 5 months instead of 4 is almost always simply a baby being a baby — the checkpoints are spaced out precisely because the normal range is wide. The examples below follow the CDC checklists (checked November 2026).

Tip: this table scrolls sideways on small screens.

Two honest notes about this chart. First, it shows examples — the full CDC checklists have a few more items per checkpoint, and your pediatrician works from those. Second, if you want this on paper, print this page — the chart is laid out to sit happily on a fridge door — and start with the free keepsake pack below. More charts and recording pages live in our Milestones & Keepsakes section.

Three things this chart cannot tell you

1. The range is the point

A milestone appears on a checklist when about 75% or more of babies can do it by that age. That means up to a quarter of perfectly typical babies do it a little later. One late skill, on its own, is information — not a verdict.

2. Babies develop in their own order

Some babies pour everything into movement and talk later; others chat early and cruise late. And some skip steps entirely — crawling is the famous one. It does not appear on the CDC checklist at all, because so many healthy babies go straight from sitting to pulling up.

3. A chart is not a diagnosis

Charts describe populations. Your pediatrician knows your baby — their birth history, growth and temperament. If something feels off to you, that instinct is worth a conversation at any check-up, whatever the chart says.

Before you worry: run these three checks

When a skill seems late, work through these before you spiral — they resolve most milestone anxiety honestly:

• Am I using the right checkpoint? Judge a 5-month-old against the 4-month checkpoint, not the 6-month one. Skills belong to checkpoints, not to birthdays.
• Was my baby born early? If so, use their corrected age (age counted from the due date, not the birth date) — pediatric guidance uses corrected age for development until around age 2.
• Is it one skill, or a pattern? A single late skill in one area is usually variation. Several missed skills in the same area, or in more than one area, is a pattern worth raising.

And one rule that overrides all three: if your baby loses a skill they once had, at any age, call your pediatrician promptly — that is the one milestone signal every source treats as urgent. In the very first months, sleep changes just as fast as skills do; our newborn sleep schedule by week shows what that side of the first year typically looks like.

How to record milestones so you actually keep them

Here is the quiet tragedy of the first year: the milestones you swore you would never forget blur together by month nine. The fix is boring and it works — record each first within a day, with three things: the date, a photo, and one sentence about how it happened. “Rolled over — 14 March, on the blue mat, straight after a bath, looked as surprised as we were.” That one sentence is what you will actually treasure.

Keep the record somewhere with structure — a dated page per checkpoint beats a camera roll of ten thousand unsorted photos. It is exactly the job our printable kit was made for, and the free starter pack below is the gentlest way to begin.

Questions parents ask us

What does “most babies” actually mean on this chart?

It means the skill is something about 75% or more of babies can do by that checkpoint age — the way the CDC builds its checklists. It also means up to a quarter of typical babies do the same skill a little later. The chart describes what is common, not what is required by a deadline.

My baby skipped crawling — should I worry?

Skipping crawling is common and, on its own, not a concern: crawling does not appear on the CDC checklist at all. Many babies move from sitting to pulling up and cruising without a crawling phase. Mention it at a check-up if you like, but it is a well-known variation, not a red flag.

My baby was premature. Which age do I use?

Use corrected age — your baby’s age counted from their due date rather than their birth date — when you read the chart. Pediatric guidance uses corrected age for development until around the second birthday, because early babies have simply had less time.

When should I actually call the pediatrician?

Call if your baby loses a skill they once had, at any age — that is always worth a prompt conversation. Also raise it if several skills in one area seem late together, or if your instinct keeps saying something is off. Check-ups exist for exactly these questions, and no pediatrician minds being asked.
