Your baby at 45 weeks: word watch

Medically-informed · Sources: CDC · Updated June 2026

First true words commonly appear anywhere from now through 14+ months: 'mama' aimed at mama, 'ba' meaning ball — meaning attached to sound.

What’s happening

What counts as a word

Any consistent sound aimed at a consistent thing counts — 'baba' for bottle is a word even if the phonetics need years of polish.

Understanding runs ahead

Receptive language leads: your baby likely understands 'no', own name, 'where's daddy?' and simple requests long before saying much.

The naming game

Point-and-name everything, then pause. The pause is where speech grows — leave silences for your baby to fill.

What to do

  • Keep a first-words list in notes — it becomes a treasure
  • Ask simple 'where is…?' questions and celebrate the looks/points
  • Sing the same few songs on repeat — repetition builds prediction builds words

When to check in

No response to quiet sounds or name across days — hearing check conversation with the pediatrician.
