What is happening in the brain
Between 6 and 12 months a baby learns that sounds carry meaning. They begin repetitive babbling (“ba-ba-ba”, “ma-ma-ma”), recognise their name, understand “no”, and towards 12 months say one or two meaningful words. What builds all of this is not educational video but the number of words heard from a person looking at them and turn-taking in “conversation”.
Six daily habits
- Narrate what you do. “Mum is opening your diaper. It is wet. Now a dry one.” In whichever language is most natural to you; two languages at home do not confuse babies.
- Answer the babble. When the baby says “ba”, reply “ba! yes, ball.” Wait 3 to 5 seconds for their turn. This turn-taking is the core of conversation.
- Name what they are looking at. Follow their gaze rather than redirecting it. Words spoken at the moment the baby is looking at the object stick best.
- Read a book every day, even for 5 minutes and even if they would rather chew it. Big picture books with one object per page work best.
- Sing action songs, rhythm and repetition reinforce sound patterns.
- Switch off screens. Under 18 months screens add no vocabulary and reduce real conversation time.
What to expect
- 6 months: turns to sounds, vowel babbling, laughs.
- 9 months: repetitive consonant babble, understands “no”, points or reaches while vocalising.
- 12 months: waves “bye”, responds to their name, 1 to 2 words like “mama” or “dada” with meaning.
When to seek an evaluation
If at 9 months there is no consonant babbling or no turning to sounds, or at 12 months no pointing and no response to their name, ask your doctor to check hearing and development. Tick milestones in Tumbuh → Milestones so the pattern is visible early.
