Motor milestones, in plain words

They are the movement skills babies pick up in time, like sitting, crawling and walking.

What are motor milestones?

Motor milestones are the movement skills a baby gains in order: holding up the head, rolling, sitting, crawling, standing and walking. “Motor” simply means movement.

They are used as a guide to see how a child is developing, not as a race or a test.

Why does it matter for parents?

Parents compare their baby with cousins and neighbours, and worry when another child walks first. Healthy babies reach milestones across a wide window of ages.

The World Health Organization (WHO) followed 816 children from five countries, and found that healthy children walked alone anywhere between 8.2 and 17.6 months [1]. The same study found that not every baby crawls on hands and knees, and this alone is not a problem.

When should we ask for a check?

Ask your child’s doctor or a physiotherapist if your baby has stopped doing something they could do before, is very stiff or very floppy, favours one side of the body, or is well past the usual window for a skill.

Trust your own sense. It is fine to ask early, and a check usually reassures.

An everyday example in Ipoh

A mother in Bercham notices that her friend’s baby walked a few months earlier than hers. She writes down what her own baby can do: sits steadily, pulls to stand, and cruises along the sofa.

At the clinic visit, the doctor reviews her notes, finds nothing worrying, and suggests more play time on the floor.

  • Tummy time: supervised play on the tummy that builds strength.
  • Hypotonia: low muscle tone, a floppy feel.

Questions people ask

My baby is not crawling. Is that a problem?

Not by itself. Some healthy babies bottom-shuffle or go straight to standing and walking. Look at the whole picture: is your baby moving all limbs, using both sides and getting stronger? If you are unsure, ask your doctor or a physiotherapist.

Do baby walkers help babies walk sooner?

No. Baby walkers can slow floor skills and bring risks of falls and burns. Floor play with safe space to roll, crawl and pull up is better. Read our page on baby walkers and development for more.

What should I bring to a check?

Bring the baby's health book, notes on what they can do and what worries you, and a short video of the movement if you can. Tell the clinician about birth history and any illnesses, because these help the assessment.
