Every parent watches their child grow with a mixture of wonder and quiet worry. Is she on track? Why is he not walking yet? Should she be talking more by now? These questions are natural — and having a reliable reference for developmental milestones can help you celebrate achievements and recognise when professional guidance might help.
Remember: milestones represent what most children can do by a certain age. There is always a range of normal development. However, if your child is missing multiple milestones in an age group, or if you have a gut feeling something is not right, a professional assessment is always the right next step.
Important note: These milestones are general guides, not diagnostic criteria. If you are concerned about your child's development at any age, contact a qualified therapist for an individualised assessment. Early intervention always produces better outcomes than waiting.

Seek a professional assessment if your child:
- Is consistently missing milestones across two or more age categories
- Loses skills they previously had (regression)
- Has a significant imbalance — very advanced in some areas, very behind in others
- Shows limited social interest, poor eye contact, or unusual repetitive behaviours
- Has a history of prematurity, birth complications, or known medical conditions affecting development
