What are the NHS milestones?
The UK National Health Service publishes early-childhood development guidance through its Start for Life programme. It describes what most children do at each stage from birth through five years, helping families know what to look out for and when to ask a health visitor for support.
How it is structured
Milestones are set out by age and grouped into four areas — Cognitive, Language-Communication, Movement-Physical, and Social-Emotional. The guidance is written for parents, so each item describes an everyday, observable behaviour rather than a clinical test.

Milestones appear grouped by area and age as one independent reference on typical timing. Learning Curve synthesises this alongside other sources and does not present it as medical advice.
