Parents are told constantly that every child is different, and that is true. It is also the reason genuine developmental delays are frequently identified late, because concerns are dismissed with the advice to wait.
Some variation is normal. Certain specific absences are not, and identifying them early makes a substantial difference.
The Four Areas of Development
Development is assessed across four domains, and a child may be advanced in one and behind in another.
- Gross motor: head control, sitting, crawling, walking, running
- Fine motor: grasping, transferring objects, pincer grip, drawing
- Speech and language: both understanding and expression
- Social and emotional: smiling, eye contact, joint attention, play with others
Delay confined to one area, most often speech, has a different significance from delay across all four. Global delay affecting every domain warrants a fuller assessment.
Milestones in the First Year
These are the ages by which most children have achieved each skill.
- 2 months: social smile, follows objects with eyes, lifts head briefly
- 4 months: good head control, reaches for objects, laughs
- 6 months: sits with support, transfers objects between hands, babbles, responds to their name
- 9 months: sits unsupported, crawls or shuffles, babbles in strings such as mama and dada, shows stranger awareness
- 12 months: pulls to stand, may take steps, pincer grip, one or two meaningful words, waves and points
Pointing at twelve months is more significant than most parents realise. A child who points to show you something is demonstrating shared attention, which is a key social and language foundation.
The Second and Third Years
Language accelerates dramatically in this period.
- 18 months: walks well, six to ten words, follows a simple instruction, points to body parts
- 2 years: runs, around fifty words, joins two words together, follows two step instructions, uses a spoon
- 3 years: three word sentences, speech understandable to strangers about three quarters of the time, plays alongside other children, climbs stairs alternating feet
- 4 years: full sentences, tells a simple story, plays cooperatively, draws a person with a few parts
Understanding usually runs ahead of speaking. A child who follows instructions well but speaks little has a different problem from one who neither understands nor speaks, and the second is more concerning.
The Red Flags Worth Acting On
These specific absences warrant assessment rather than waiting.
- Any age: loss of skills the child previously had. This always requires prompt assessment
- 3 months: no social smile, no response to sound
- 6 months: no reaching, poor head control, not turning to sound
- 9 months: no babbling, no response to their name
- 12 months: no pointing, no gestures, no single words
- 18 months: fewer than six words, no interest in other people
- 24 months: no two word phrases, not following instructions
- Any age: not walking by eighteen months, persistent toe walking, or marked asymmetry in movement
Regression, the loss of a skill, is the most important item on this list. A child who was saying words and has stopped needs to be seen quickly.
Hearing Is the First Thing to Check
The most common treatable cause of speech delay is hearing impairment, and it is frequently missed because a child with partial hearing loss appears to respond selectively.
Recurrent middle ear fluid, common in young children, causes fluctuating hearing loss during exactly the period when language is being acquired. Persistent congenital hearing loss is less common but far more consequential.
Any child with speech delay should have a formal hearing test, not a judgement based on whether they turn to a clap. Our ENT department performs paediatric hearing assessment.
Bilingual Homes Do Not Cause Delay
This myth causes real harm, because families are advised to drop their home language and the child ends up with weaker input in both.
Children raised with two or more languages reach milestones at the same ages when total vocabulary across languages is counted. They may mix languages within sentences, which is normal and resolves.
A bilingual child with genuine delay has delay in both languages. Delay in one language only reflects exposure, not disorder. Continue speaking your home language fluently, since rich input in any language builds the foundation.
Why Early Intervention Matters
The brain is most adaptable in the first three years, and therapy delivered during that window achieves considerably more than the same therapy started at five.
Waiting to see whether a child catches up is the most common reason intervention starts late. If a child does catch up, therapy did no harm. If they do not, the delay in starting cannot be recovered.
Developmental assessment identifies which areas need support, and intervention may involve speech therapy, occupational therapy, physiotherapy or structured early education.
What Parents Can Do at Home
Everyday interaction is the most powerful language input a child receives.
- Narrate what you are doing throughout the day
- Get down to the child's eye level when speaking
- Pause after speaking to give them time to respond
- Expand on what they say, so if they say car you say big red car
- Read together daily from infancy, pointing at pictures
- Sing rhymes, which build rhythm and sound awareness
- Avoid screens under two years and limit them sharply after
- Do not correct pronunciation constantly, instead model the correct word back
Screen time is the most significant modifiable factor we see. Passive viewing does not build language, and it displaces the interaction that does.
Trust your instinct. Parents who feel something is different are frequently right, and a normal assessment costs little while a delayed one costs a great deal. Loss of skills, absent pointing at twelve months and no two word phrases at two years are the three items worth acting on immediately.
