Speech Development

This table shows which sounds are expected to develop by which age.

It can be difficult to know exactly which sounds your child is and isn’t using properly.  Another guide it to ask yourself this question:

“How well do I understand my child?”

  • 18months old                           Expect him to be 25% intelligible
  • 2 years old                                Expect her to be 50 -75% intelligible
  • 3 years old                                Expect him to be 75 – 100% intelligible

If your child is 3 or older, you should be able to understand them nearly all of the time.  If you cannot understand your 3 year old, please phone for an assessment.
