Baby First Year Guide: Month-by-Month Milestones

"The first year feels like the most important exam I've ever had to take. Nobody gave me the study guide."

Who it's for — first-time parents who want to know what is coming, what is normal, and what genuinely warrants a call.

The problem — milestone information is scattered across apps that alarm you and leaflets that tell you nothing. Neither gives you the shape of the year.

What's inside — month-by-month development across feeding, sleep, movement, communication and social skills, with the wide normal ranges made explicit.

The transformation — from anxious milestone-checking to understanding the direction of travel.

The first year in four stages

Months	Movement	Communication
0–3	Head control, tracking faces	Cooing, first social smile
4–6	Rolling, reaching, sitting with support	Babbling, responds to name
7–9	Sitting unaided, crawling, pulling up	Consonant strings, gestures appear
10–12	Cruising, first steps for some	First words, pointing, waving

Ranges are wide and the order varies. Some babies skip crawling. Walking anywhere from nine to eighteen months is within normal.

Who this guide is not for

It is not a diagnostic checklist, and it is deliberately not designed to be scored. If you are looking for something to tick off weekly, this will read as too relaxed. If your child has a diagnosed developmental condition, their care team's guidance supersedes anything here.

Frequently asked questions

My baby is behind on one milestone. Should I worry?
A single milestone slightly late, with everything else on track, is usually not concerning. Patterns across several areas, or loss of a skill already gained, are what warrant a conversation.

Does prematurity change the timeline?
Yes. Milestones are usually tracked against corrected age until around two years. The guide explains how to apply that.

Is this useful for a second baby?
Often more useful, because you already know the questions worth asking.
