1οΈ Communication Timeline: Birth to 18 Months
Communication happens long before words. Understanding the full picture helps you know what to expect.
Newborn β 2 months:
- Crying is communication β different cries for hunger, pain, tiredness
- Startles to sound
- Quiets to familiar voices
- Makes soft cooing sounds
- β Watch for: Turns toward sound; responds to your voice
2 β 4 months:
- Social smiling starts
- Coos, gurgles, "talks back" when you talk
- Vowel sounds appear: "ooh," "ahh"
- Laughs (around 4 months)
- Pays attention to where sounds come from
- β Watch for: Takes turns "talking" β you speak, they respond
4 β 6 months:
- Babbling begins: "ba," "da," "ma" (not words yet β just sounds)
- Vocalizes to show happiness and displeasure
- Recognizes name
- Responds to tone of voice
- β Watch for: Babbling with varied consonant sounds
6 β 9 months:
- Babbling becomes more complex: "babababa," "dadada"
- Uses gestures: raises arms to be picked up
- Understands "no" (even if they ignore it!)
- Recognizes common words: "bottle," "ball," "mama"
- Points to get attention (proto-declarative pointing)
- β Watch for: Responding to name, babbling, beginning gestures
9 β 12 months:
- "Jargon" β babbling that sounds like real sentences with intonation
- May say 1β3 real words (or none yet β completely normal)
- Follows simple commands with gesture: "come here"
- Waves bye-bye, claps hands
- Points at objects
- β Watch for: Jargon, following simple cues, pointing
12 β 18 months:
- 1β5 words typically by 12 months (range: 0β10)
- Vocabulary explodes around 18 months (20β50 words)
- Says "mama" and "dada" meaningfully
- Understands far more than they say
- Points to body parts when asked
- β Watch for: 1+ words, pointing, following 2-step commands
Important: Understanding (receptive language) is always ahead of speaking. A baby who follows instructions and points but hasn't said words yet is often doing fine.
