Language acquisition is the process by which a child learns to understand and use language. It moves from cooing and babbling in the first year to a first word around 12 months, word combinations around 2 years and sentences after that.

What are the main stages?

Typical stages in the first years:

AroundWhat you may notice
2 monthsCooing: soft vowel sounds
6-9 monthsBabbling: "ba-ba", "da-da"
9-12 monthsUnderstanding simple words, waving and pointing
12 monthsFirst meaningful words
18 monthsGrowing vocabulary, often quickly
2 yearsTwo-word phrases such as "more milk"

What you can do

  • Talk, read and sing with your child every day.
  • Respond to your child's sounds and words as conversation.
  • Limit background TV and screens.

When to talk to your doctor

Talk to your doctor if your baby is not babbling by 10 months, has no words by 15-18 months, is not combining words by 2 years, or loses words they used to say.
