Red flags
- Loss of previously acquired language or social skills at any age
- No babbling by 12 months
- No single words by 16 months
- No meaningful two-word phrases by 24 months
- Absent or markedly reduced joint attention, pointing or name response in the expected window
- Language concern with no hearing pathway arranged
- Strong caregiver concern dismissed because the child is 'just shy' or bilingual

Three overlapping skills
Language and speech
Social communication
These domains travel together in clinic. A toddler with many words but no pointing needs a different pathway from a late talker who understands well and points to request. [1] [4]
Overview & Definition
Normal language development is the expected acquisition of understanding, words, grammar and speech sounds. Communication is broader. It includes prelinguistic skills such as eye gaze, cry patterns, babble and gesture. Social communication is how the child uses these skills with other people: sharing attention, requesting, commenting and later conversing. [4] [5]
Evidence-informed milestone lists now emphasise skills achieved by most children at a given age, not historical “average ages” that false-reassured families. That change matters for surveillance tools and for what you say in clinic. [1]
This page owns normal trajectories, bedside observation and anticipatory guidance. Cross-link surveillance technique, validated screening tools, speech-language delay work-up and autism recognition rather than hiding full specialty chapters here. [2]
