Quick answer: Most babies say ‘mama’ and ‘dada’ with meaning — directed at the right parent — between 10–14 months. Babbling these sounds without meaning starts much earlier, typically 6–9 months. By 12 months, at least one meaningful word is the developmental milestone.
The stages of babbling to words
Pre-linguistic vocalisation develops in a predictable sequence. 0–2 months: cooing (soft vowel sounds, ‘ooh’, ‘aah’). 3–6 months: vocal play — experimenting with pitch, volume, and sound production, increasingly varied sounds. 6–9 months: canonical babbling begins — repeated consonant-vowel combinations: ‘bababa’, ‘mamama’, ‘dadada’. At this stage, ‘mama’ and ‘dada’ are purely phonological — the baby is practising consonant-vowel combinations, not labelling their parents. 10–14 months: first meaningful words emerge — the same sounds become directed, consistent, and contextually appropriate (looking at mom and saying ‘mama’; reaching toward a cup and saying ‘wa’ for water).
How to know when it’s meaningful
The shift from babble to word is characterised by three things: directedness (the sound is produced while looking at or reaching toward the specific person or object), consistency (the same word used for the same referent across multiple occasions), and generalisation (the word is used to label the same category in different contexts — ‘mama’ for mom in the kitchen and mom in the garden, not just in one specific spot). A baby who says ‘dada’ while staring at the ceiling and also when looking at Dad has not yet attached meaning. A baby who specifically turns toward their father and says ‘dada’ has.
First words beyond mama and dada
In English-speaking households, first words most commonly are: ‘mama’, ‘dada’, ‘no’ (usually high-frequency, highly reinforced), object names for frequently used items (cup, dog, ball, more), and social words (‘hi’, ‘bye’, ‘uh-oh’). By 12 months the milestone is any clear first word. By 18 months: minimum 10 words. By 24 months: minimum 50 words and two-word combinations. These are the thresholds for referral — not personal targets, but the points at which speech and language evaluation is recommended.
Language environment matters
The single most modifiable factor in language development is the volume and quality of speech the baby hears from birth. Research by Hart and Risley (1995) and replicated studies show that the number of words a child hears in the first 3 years directly predicts vocabulary at school age. Strategies with evidence: talking to your baby from birth about everything you’re doing (narrating daily tasks); following the baby’s eye gaze and naming what they’re looking at (joint attention labelling); responding consistently to vocalisations (turn-taking); reading aloud daily from any age; and reducing background TV which reduces the quality of child-directed speech.
Frequently Asked Questions
My 9-month-old says ‘mama’ but doesn’t seem to mean me specifically — is that normal?
Completely normal. At 9 months, ‘mamama’ is typically still babble — practising the consonant-vowel combination without specific meaning attached. Meaningful ‘mama’ directed specifically at you usually emerges at 10–14 months. Continue responding warmly to the babble (‘Yes! Mama is here!’) — this reinforces the sound-meaning connection.
My 15-month-old has no words at all — what should I do?
Request a referral to a speech and language therapist (SLT) from your doctor or pediatrician. 15 months with no words is below the expected range (milestone is 1 word by 12 months, ideally a small vocabulary by 15 months). Also: check hearing. A hearing assessment should be the first step when speech delay is identified, as undetected hearing loss is a common and treatable cause.
My baby says mama and dada but says dada more — does that mean they prefer their dad?
Not necessarily — ‘dada’ typically appears before ‘mama’ in many babies because the ‘d’ consonant is often easier to produce than ‘m’, despite ‘m’ appearing in babble too. The relative frequency of use at this stage is more about phonological ease than emotional preference.
