What parents should know
The main areas of development
Gross motor skills cover head control, sitting, crawling, walking and running. Fine motor skills cover reaching, grasping, transferring objects and later drawing and self-feeding. Communication includes babbling, understanding, first words and sentences. Social and emotional development covers eye contact, shared attention, play with others and daily living skills.
Progress in these areas overlaps. A child concentrating on walking may pause in speech for a short period, then catch up. Premature babies are usually assessed using corrected age in the early years.
- Movement and posture
- Hands, grasp and self-feeding
- Understanding and speech
- Social interaction and play
Normal variation and what it means
Wide variation is expected. Some children walk at nine months and others near eighteen months, and both can be entirely healthy. Family patterns, temperament, opportunities to play and move, illness and hearing all influence the pace. Online checklists can help you organise what you have noticed, but they are not diagnostic tools and cannot replace an examination.
When to seek assessment
Ask for a review when a child loses a skill they previously had, when progress has clearly stalled, when you are concerned about hearing or vision, when speech is much later than peers, when muscle tone seems unusually stiff or floppy, or when interaction and play differ noticeably from other children of the same age. Earlier assessment usually means earlier support.
Bring your observations, any previous growth or health records, school or caregiver feedback, and short home videos if they illustrate your concern.
Seek urgent medical care now if
- • Loss of a skill the child previously had, such as speech, walking or social response
- • New weakness, floppiness, persistent stiffness or asymmetric movement
- • A seizure, altered consciousness or unresponsiveness
- • No response to sound or no visual following that concerns you
- • Sudden behavioural or developmental change during an acute illness
Do not wait for an online reply or routine clinic appointment when a child has emergency warning signs.
See all emergency red flagsQuestions parents ask
My child is a late walker. Should I be worried?
Walking has a wide normal range. It is worth an assessment if the child is not walking by around eighteen months, seems unusually stiff or floppy, or if other areas of development are also delayed.
Does a milestone checklist diagnose a developmental delay?
No. A checklist helps you describe your observations. A diagnosis needs history, examination and sometimes hearing, vision or developmental assessment.
What should I bring to a developmental consultation?
Previous growth and health records, vaccination record, notes on what you have observed and when, feedback from school or caregivers, and short videos if a behaviour is difficult to describe.
