Key point: language begins long before the first “mama” or “dada”. Babies communicate through gaze, facial expressions, cries, sounds, gestures and babbling before using words. Developmental milestones describe a trajectory, not a competition.
What helps most is repeated human interaction: responding to sounds and gestures, talking during routines, sharing books, singing, naming what interests the child and leaving time for a response.
Language starts at birth
A newborn cannot speak, but is already communicating. Babies respond to voices, watch faces and gradually discover that their signals produce responses from adults. This back-and-forth is one of the foundations of communication.
The WHO places these interactions within nurturing care: children need health, nutrition, safety, responsive caregiving and opportunities for learning from birth.
0 to 6 months: voices, faces and early sound play
During the first months, sounds become more varied. Babies vocalise, laugh, coo and increasingly react to people. Simple face-to-face interaction, talking and singing during routines all provide opportunities to hear language.
Around 6 months: babbling becomes richer
Babbling allows babies to explore mouth movements, voice control and the sounds they hear around them. When an adult responds, sound play becomes an exchange.
Gestures and understanding often come before words
Before having an oral vocabulary, a baby may understand routines, recognise some words, reach out, point, give objects or use social gestures. Counting words alone therefore gives an incomplete picture.
Around one year: first words
First words often appear around one year, with substantial individual variation. A word does not have to sound exactly like adult pronunciation to carry meaning if the child consistently uses the same approximation for the same thing.
12 to 18 months: a highly variable period
At 18 months, the CDC lists trying to say three or more words besides “mama” or “dada” and following a one-step direction without gestures among its milestones. One missing milestone is not a diagnosis.
18 to 24 months: words begin to combine
At age two, the CDC includes saying at least two words together, pointing to things in a book when asked and using a wider range of gestures among its milestones.
Why are everyday routines so useful?
Bath time, meals, dressing, walks and tidying are repetitive. Repetition helps children connect words with actions and objects. Language grows through everyday life.
Follow the child's interest
If your toddler is watching a truck, talking about the truck usually makes more sense than imposing an unrelated vocabulary exercise. Shared attention helps connect the word heard with what the child is noticing.
Should I ask my child to repeat words?
Occasionally it can be a game, but constant requests to repeat can turn conversation into a test. A more natural strategy is modelling the word in context.
Are books useful before a baby can talk?
Yes. A board book may mean looking at two pages, touching a picture or pointing to an animal. Follow the child's pace rather than expecting a complete story.
Two languages at home
Growing up with more than one language is not, by itself, a language disorder. Vocabulary may be distributed across languages, so meaningful assessment considers all languages the child hears and uses.
Screens and language
A video saying words does not provide the same reciprocal exchange as a person who notices what the child is looking at and responds to gestures. For very young children, prioritise real interaction.
When should parents seek advice?
Speak to a healthcare professional if you think your child does not hear well, stops responding to sounds, loses previously acquired abilities, communicates very little or stops progressing. These signs justify assessment but do not allow parents to diagnose a disorder themselves.
Why consider hearing?
Access to speech sounds matters for language development. Some hearing losses are subtle or fluctuate, so hearing is one of the factors to consider when language development is concerning.
Regression should always be reported
Losing words, gestures or communication abilities that were already established is different from learning more slowly. Report regression promptly to a healthcare professional.
Key takeaways
Language development is neither a race nor a miniature school programme. Babies listen, look, babble, point, understand and gradually use words and sentences. Age milestones are useful when they help identify a difficulty, not when they become a constant source of comparison.

Developmental milestones describe population patterns and do not replace individual assessment. If skills regress, hearing is in doubt or concerns persist, speak to a healthcare professional.
