By about 4 months, babies start to babble, with pitch that rises and falls like speech. After 6 or 7 months, they begin to copy the sounds they hear. Syllables like “ba”, “da” and “ma” follow.

First words don’t have to be proper English. A sound your baby uses every time for the same thing counts as a word. Babies also understand far more than they can say.

What can help

  • Talk through what you’re doing at bath time, changes and meals.
  • Use simple words, and name familiar things the same way each time.
  • Read picture books with large pages.
  • Ask questions, wait for a response and repeat your baby’s sounds back to them.

When to ask

The AAP says to let your pediatrician know if your baby doesn’t babble or copy any sounds by their seventh month, so their hearing and speech can be checked. If you have any questions about your baby’s development, it says to ask, the sooner the better.
