Is late walking a sign of a problem?

Usually not on its own. Independent walking spans roughly nine to eighteen months normally. It carries more weight when it comes alongside other delays, or with unusual stiffness or floppiness.

Does being bilingual delay speech?

No. Bilingual children reach communication milestones on a comparable schedule; their words are simply distributed across two languages, so counting only one undercounts them.

What if the evaluation finds nothing?

That is a good outcome and not a wasted appointment — it converts an open worry into an answer, and it establishes a baseline if anything changes later.

When it happens · 5 min read

Everyone else's baby is doing it and yours isn't

Comparison is unavoidable, and the charts make it worse by implying a schedule that children were never on.

There are two things genuinely worth knowing here: what the checklists actually claim, and how little standing in your way there is if you want a proper look.

The checklists changed, and it matters

Until 2022 the milestone lists broadly marked the average age for a skill, which meant half of all typically-developing children were 'behind' by definition, and the lists generated enormous anxiety for no gain.

They now mark what about 75% of children can do by a given age. That makes a missed item more meaningful than it used to be, and it makes the current list a better prompt for a conversation. If you are comparing against something remembered from a first child, you may be comparing against the old framing.

Ranges are wide and mostly boring

Independent walking anywhere from about nine to eighteen months is within the ordinary range. Some children skip crawling entirely. Bottom-shuffling is a legitimate form of getting about and not a warning sign on its own.

What is more informative than any single skill is the overall pattern: is the child progressing, communicating in some way, socially engaged, and steadily adding to what they can do. A child moving forward on a slower timetable looks very different from one who has stalled.

You can ask for an evaluation yourself

This is the part almost nobody is told. Under IDEA Part C in the US, a parent can request an early-intervention evaluation directly — no physician referral required — and the programme is obliged to respond within a defined timeframe. Evaluation is free regardless of income.

'Let's wait and see at the next visit' is sometimes right and is often just the path of least resistance. If you are worried, requesting the evaluation costs you a phone call and resolves the question with actual assessment rather than more waiting.

Bring specifics rather than a feeling. 'He has maybe fifty words and doesn't put two together' gives someone a place to start; 'he seems behind' does not.

The pattern that always warrants a call

Losing a skill that was previously established — words that have gone, waving or pointing that has stopped, walking that has regressed — is categorically different from being slow to acquire one, and it is worth a prompt call rather than watchful waiting.

Also worth raising promptly: no babbling or gestures by around a year, no single words by around sixteen months, no two-word phrases by two, no response to their name, or a marked lack of interest in other people.
