Red Flags in Communication Development
Red flags in communication development include limited eye contact or shared smiling in infancy, no babbling by 12 months, no single words by 16 months, no two-word phrases by 24 months, any loss of words or skills once gained, and few gestures like pointing or waving. Communication has a wide normal range, so these are signs to observe and act on early, not to diagnose at home. A persistent or widening delay, more than one area affected, or any loss of skills is always worth a prompt check — starting with hearing.

Communication grows in tiny steps — eye contact, a shared giggle, a first word — so how do you tell a slow-but-steady pace from a pattern worth a closer, kinder look?
In short
Red flags in communication development include little eye contact or shared smiling in infancy, no babbling by around 12 months, no single words by 16 months, no two-word phrases by 24 months, loss of words or skills once gained, and limited gestures like pointing or waving. These are signs to observe and act on early — not to diagnose at home. Communication has a wide normal range, but a clear delay, a plateau, or any loss of skills is always worth a prompt check.
Communication red flags to watch (by age)
Communication is more than talking — it is connecting, understanding and being understood.
Babies (birth–12 months)
- Little eye contact, shared smiling or response to familiar voices
- Not turning to sounds or their name by around 9–12 months
- No babbling ("bababa", "dada") by about 12 months
- Few gestures — no waving, pointing or reaching to be picked up
Toddlers (12–24 months)
- No single meaningful words by 16 months
- Not following simple instructions ("give me the ball")
- No two-word phrases ("more milk") by 24 months
- Loss of words, babble or social skills once present — always check promptly
Young children (2–4 years)
- Speech very hard for family to understand
- Little back-and-forth conversation or pretend play
- Not asking simple questions or naming familiar things
What shifts these from ordinary variation towards assessment is a delay that persists or widens, more than one area affected (understanding and speaking), or any loss of skills. A hearing check comes first, since hearing affects every part of communication.
When to seek a check
Bring any concern about understanding, speech, gestures or social connection to your paediatrician or a speech therapist early — you never need a label to begin gentle support, and acting early makes the biggest difference.

Bring your questions to a first visitQuestions families ask
By what age should my child say their first words?
Most children say single meaningful words by around 12–16 months and combine two words (like "more milk") by about 24 months. Communication has a wide normal range, but no single words by 16 months or no two-word phrases by 24 months is worth a prompt check, starting with hearing.
My child babbled and said a few words, then stopped. Is that serious?
Any loss of words, babble or social skills once gained should always be checked promptly with your paediatrician or a speech therapist. It is not something to wait and watch — early review helps understand what is happening and how best to support your child.
Is communication only about talking?
No — communication includes understanding, eye contact, gestures like pointing and waving, shared smiling and back-and-forth interaction. A child can have strong understanding before clear speech, so we look at the whole picture, not words alone.
What should I do first if I'm worried?
Start with a hearing check, since hearing shapes every part of communication, and raise your concern with your paediatrician or a speech therapist. You never need a diagnosis to begin gentle, play-based support — acting early makes the biggest difference.
