What this tool does

It gives you a quick, age-specific picture of what most children can typically do at a given stage, so you can see whether your child is broadly on track or whether something might be worth a closer look.

The checker covers four areas: physical skills like crawling, walking and fine motor control, thinking and learning, social and emotional behaviour, and talking and understanding language. You will get a plain English summary rather than a pass or fail score, because children vary a lot and most differences are nothing to worry about.

Who it is for

It is aimed at parents, grandparents, childminders and anyone else in the UK who spends regular time with a child from birth up to around five years old. You might use it if you have a quiet worry that your little one is not babbling as much as other babies the same age, if a nursery has mentioned something, or if you simply want to know what to expect before the next health visitor review.

It is not a diagnostic tool and it does not replace advice from your GP, health visitor or paediatrician. If your child was born prematurely or has a known condition, treat the results as rough guidance only, as their milestones will often follow a different timeline.

How it works

You enter your child's age in months or years, then answer a short set of yes or no questions about what they can currently do. The tool compares your answers against the milestones most children reach by that age and shows you which areas look on track, which fall within normal variation, and which might be worth raising with a health professional. You do not need to create an account, and nothing you enter is saved once you close the page. If the results suggest a chat with your GP or health visitor would be sensible, we will say so clearly and explain what to mention when you get in touch.
