"Is my child developing normally?" is one of the most common questions parents ask at every well-child visit — and for good reason. A child's early years are a period of rapid growth across multiple areas at once: movement, communication, thinking, and social-emotional skills. While the range of "normal" is wide, developmental delay — when a child consistently lags behind expected milestones in one or more areas — is worth identifying early, because early support tends to make the biggest difference.
Understanding the Domains of Development
Pediatricians typically assess development across five broad domains:
- Gross motor skills — sitting, crawling, walking, running, climbing
- Fine motor skills — grasping, transferring objects between hands, using a spoon, drawing, writing
- Speech and language — understanding words, babbling, first words, combining words into sentences
- Cognitive skills — problem-solving, object permanence, pretend play, understanding cause and effect
- Social-emotional skills — smiling, eye contact, interacting with caregivers, playing with other children, regulating emotions
A child can be delayed in just one domain (for example, speech alone) or across several — which is sometimes called global developmental delay.
Key Milestones by Age
The table below outlines commonly used milestone guidelines. Remember that these are general guides, not strict deadlines — but a child missing several milestones for their age, or losing previously gained skills, should be discussed with a pediatrician.
| Age | What Most Children Can Do |
|---|---|
| 6 months | Sits with support, brings hands/objects to mouth, babbles, smiles and laughs responsively |
| 12 months | Pulls to stand, may take first steps, waves bye-bye, says "mama"/"baba" or similar, responds to name |
| 18 months | Walks independently, says several single words, points to show interest, imitates simple actions |
| 2 years | Runs, kicks a ball, uses 2-word phrases, follows simple 2-step instructions, engages in simple pretend play |
| 3 years | Climbs stairs, speaks in short sentences understood by familiar adults, plays alongside other children, names some colours |
| 4-5 years | Hops/balances on one foot, tells simple stories, follows multi-step instructions, plays cooperatively, manages basic self-care (dressing, using the toilet) |
Signs That May Indicate a Delay
- Not sitting without support by 9 months, or not walking by 18 months
- No babbling by 12 months, no single words by 16 months, or no 2-word phrases by 24 months
- Limited eye contact, or not responding to their name by 12 months
- Difficulty with simple instructions appropriate for age
- Loss of previously acquired skills (regression) at any age
- Significant difficulty with feeding, chewing, or coordination compared to peers
Common Causes of Developmental Delay
Developmental delay can have many different causes, and often no single cause is identified. Possible contributors include:
- Prematurity or low birth weight, which can affect the pace of early development (see our guide on caring for a low birth weight newborn)
- Genetic conditions (such as Down syndrome or other chromosomal differences)
- Hearing or vision impairment, which can affect language and social development if undetected
- Neurodevelopmental conditions such as autism spectrum disorder (see autism and ADHD)
- Limited stimulation or interaction in the early environment
- Chronic illness that affects energy, growth, or attendance at school/daycare
In many cases, the cause is never fully identified — and that's okay. What matters most is recognising the delay and beginning appropriate support as early as possible.
How Developmental Delay Is Evaluated
A pediatric evaluation typically includes:
- A detailed history — pregnancy, birth, and the child's developmental progress so far, plus family history
- A physical examination, including growth, vision, hearing screening, and a neurological assessment
- Standardised developmental screening tools appropriate for the child's age
- Referral, where needed, to specialists — speech-language therapists, occupational therapists, audiologists, or developmental pediatricians — for more detailed assessment and therapy planning
Why Early Intervention Matters
A child's brain develops most rapidly in the first few years of life, which is also when it is most responsive to therapy and environmental input. Starting speech therapy, occupational therapy, or structured early-learning support during this window — rather than waiting "to see if they grow out of it" — gives children the best chance of catching up to their peers, or of developing effective strategies to work with their individual strengths.
If you have any concern about your child's development, trust your instincts and get it checked. Dr. Yasser Masood offers developmental assessments for children of all ages at Shifa International Hospital, Islamabad, and can guide you toward the right specialists if further support is needed.

Final Thoughts
Most children develop within the wide range of "normal" — but when a delay is real, time matters. A short developmental screening costs little and causes no harm; missing a genuine delay, on the other hand, can mean losing valuable months or years of the window when intervention works best. When in doubt, ask.
