Milestone charts are responsible for a great deal of unnecessary worry, and occasionally for dangerous reassurance. Both come from the same mistake: treating an average as a deadline.
What a milestone age actually is
When a chart says children walk at twelve months, that is roughly the middle of a wide range. A large proportion of entirely typical children walk meaningfully later. The chart is describing a population, and your child is not a population.
Two things follow. Being later than a chart, on its own, means very little. And a child who is “on time” for everything can still have something worth looking at, because timing is not the only thing that matters.
The milestones that carry real information
Some tell you much more than others — generally the social and communicative ones, because they show the machinery of connection working.
Responding to their name by around the first birthday, most of the time, from a familiar voice at close range.
Pointing to show — not just to request. The child sees something interesting and points so you will look too. This one matters enormously and is easy to overlook.
Checking your face. Something surprising happens and they glance at you to see what you make of it.
Bringing things to show you, with no purpose except sharing.
Back-and-forth play. Peekaboo, rolling a ball, copying a noise — turn-taking for its own sake.
Understanding more than they say. Following a simple instruction with no gesture to help.
These matter more than word counts because they are what language is built on. A child with few words who does all of these is in a very different position from one who does none.
The ones that worry parents more than they should
Not crawling — some children bottom-shuffle or go straight to walking. Late walking in a child who is otherwise sociable and understanding. Being later to talk than an older sibling. Fussy eating. Shyness with strangers. Not knowing colours or numbers at three.
The ones that should never be waited out
Regardless of ages and charts:
- Losing a skill they previously had
- Not responding to sound
- Marked asymmetry — using one hand and ignoring the other in the first year
- Persistent stiffness or floppiness
These are not “behind schedule”. They are different in kind, and they deserve an appointment now.
The better question
Rather than “is my child on track?”, ask “is my child moving forward?” A child who is behind but steadily gaining is usually fine. A child who has been in the same place for months is worth looking at, whatever the chart says.
And notice the shape. Behind in one area with everything else strong points somewhere specific. Behind across the board points somewhere more general.
If you are worried
You are allowed to ask without meeting a threshold. Parents are usually right that something is different even when wrong about what — and a baseline taken now is worth having, whatever the answer.
Where we fit
We see children from infancy at our centres in India and the UK. If you are weighing up whether to ask, developmental delay and how we assess will tell you what an appointment involves.
