Growth, Development & Early Intervention
Interpret growth trajectories and developmental concerns rather than isolated measurements.
Quick revision ↓ Medical Dictionary
01Measure carefully
Plot weight, length or height and relevant head circumference on an appropriate chart. Use reliable technique and consider corrected age after prematurity according to the chart guidance. A measurement error can create an apparent growth problem, so check unexpected results before drawing conclusions.
02Follow the trajectory
Interpret serial growth alongside birth size, parental stature, nutrition and health. Crossing centiles may require assessment but is not a diagnosis by itself. Review feeding, chronic symptoms and social circumstances; a stable small child and a child with falling growth need different reasoning.
03Developmental domains
Assess gross motor, fine motor, language, social and adaptive abilities through history and observation. Milestones have a range, and hearing or vision difficulties can affect performance. Consider opportunities and language environment without dismissing persistent concerns as merely individual variation.
04Regression is a warning
Loss of previously acquired skills needs prompt assessment, particularly with seizures, weakness or abnormal neurological findings. Distinguish regression from slow acquisition or a temporary effect of illness. Do not advise prolonged watchful waiting when a child is clearly losing function.
05Support while investigating
Refer through developmental, hearing, vision and therapy pathways as indicated. Intervention need not wait for every diagnostic label. Agree meaningful functional goals with families, coordinate school or nursery support and arrange follow-up so concerns and referrals do not disappear between services.
High-Yield Revision
- Check measurement technique before interpreting a sudden change.
- Regression differs from delayed acquisition.
- Support can begin while diagnosis is being clarified.
Common Pitfalls
- Diagnosing from one centile alone.
- Ignoring hearing when language is delayed.
