Language Development: Birth–12 Months

During your baby’s first year, their language development will be somewhat limited. Early on, their main way to communicate is by crying. Babies cry because they need something: milk, a dry diaper, warmth—or they may just be lonely or uncomfortable.

But this doesn’t mean you shouldn’t expect a chatty baby. Most babies are very verbal during their first 12 months, though they won’t start forming words until close to the end of the first year. Here’s what you might expect:

0–3 Months

  • Cooing sounds

3–6 Months

  • Laughing out loud
  • Babbling (making sounds like "bah-bah," "da-da" and "ma-ma-ma")
  • Cooing

6–9 Months

  • Fussing if you take something away from them

9–12 Months

  • Beginning to say some recognizable words, such as "mama," "dada," "ba-ba," "baby" and "bird"

The first five years are critical to children’s development as their brains triple in size during that time. Research has also shown that young children who have genuine and meaningful conversations develop larger vocabularies. All of these factors are strong predictors for their long-term school success. Consider talking through your daily routines and activities with your infant child.
