💬 Communication & Language
Babbling, first words, receptive language (understanding), and expressive language from birth to 2 years.
ℹ️Source: CDC Act Early 2024 + AAP Language Development Guidelines. All milestones describe typical development ranges. Always consult your paediatrician if you have concerns about your baby's development.
📖 Overview
Language development has two streams: receptive (understanding language) and expressive (producing it). Babies understand far more than they can say — an 8-month-old may understand 10–20 words but say zero. The AAP notes that bilingual children may reach word count milestones slightly later than monolinguals but are not developmentally behind. Quality of interactions — not quantity of words passively heard — drives early language. The 'language gap' research (Hart & Risley) shows 30 million words of meaningful parent-child conversation by age 3 predicts later academic success.

🎮 Activities to Support Communication & Language
- Parentese (slow, high-pitched, exaggerated speech) — proven to accelerate language learning
- Read aloud daily from birth — label pictures, pause, let baby 'answer'
- Serve-and-return conversations — respond to every babble as if it's a word
- Narrate your actions ('I'm pouring the milk into the cup')
- Limit screen time under 18 months (AAP) — passive TV doesn't build language
- Expand on what baby says: 'More?' → 'You want more banana?'
