Late walking concerns: When to Discuss Development

If your child is not walking when you expected, you do not need to decide whether the delay is harmless before asking for help. A clinician can look at their movement, health history and progress together. The purpose of assessment is to identify useful support and any underlying problem, not to compare children competitively.
Use ages as discussion points
Most children take a few steps independently by fifteen months and walk without holding on by eighteen months. Missing an expected milestone is a reason to contact your clinician. Eighteen months is not a reason to postpone an earlier concern.
Referral guidance can use earlier thresholds for some children. Your clinician may also act sooner because of examination findings, other delayed skills or medical history. If your child was born prematurely, ask which corrected age to use. Our premature baby milestones guide explains that calculation and its limits.
Describe the movement they can manage
Tell the clinician whether your child sits independently, moves around the floor, pulls up, stands while holding on or moves along furniture. Explain whether those abilities are changing over time and whether both sides seem equally involved.
Mention frequent tiptoe positioning, unusual stiffness or floppiness, apparent pain or reluctance to bear weight. These observations do not establish a diagnosis, but they help the clinician decide what to examine. Include concerns about feeding, communication, vision or hearing rather than treating walking as an isolated skill.
Separate delay from a new loss of ability
A child who has not yet learned to walk is different from a child who previously walked and now cannot. Loss of a skill needs prompt assessment. Our developmental regression guide explains why it should not be put down to a phase without review.
Seek immediate care for a sudden inability to bear weight, a new marked change in walking, severe pain or a painful limp with fever or general illness. Sudden weakness also needs immediate assessment. Do not encourage practice through these symptoms while waiting for a routine developmental appointment.
Ask what the assessment will involve
The clinician may review the birth and medical history, observe movement and examine strength, muscle tone and joints. Depending on the findings, they may arrange developmental assessment, physiotherapy or other specialist review. Not every child needs the same tests.
Useful questions include: “What is reassuring today?”, “What still needs checking?” and “When should progress be reviewed?” Ask how to get help if symptoms change before the next appointment. A plan should include what to do if progress does not occur, not simply a request to wait indefinitely.
Keep play comfortable while arranging help
Offer safe floor play and opportunities matched to what your child can manage. Our first steps guide focuses on gentle practice. Do not buy a wheeled baby walker, force standing or start an exercise programme intended for another child.
If you remain concerned after an initial discussion, contact the clinician again and ask about further assessment. In the United States, families can also contact their local early intervention service without waiting for a diagnosis. Services and referral routes vary elsewhere, so ask your care team about the local pathway.
