Why Choose Pediatric
Speech & Language Therapy?

We provide assessment and treatment of your child’s communication skills. These include speech, language, play and interaction development. The focus of treatment may be on oral-motor skills, stuttering, tongue thrust, voice or augmentative communication, articulation, or childhood apraxia.

Toddlers and young children often have trouble with pronunciation and difficulties putting sentences together.

A child between the ages of 18 months and 3 years will generally mispronounce many words. It’s perfectly normal to have to play a guessing game to figure out what your child is saying, and at times you may have no clue what he or she is getting at. That’s okay.

If the problem is not pronunciation but rather that your child isn’t talking or is talking very little, you should act a bit more quickly. A child older than three should have clearer words and should be more easily understood. They should be able to make meaningful sentences when they are communicating ideas, and they should also be able to follow directions, ask questions and respond to questions.

You Should Have Your Child Evaluated...

       If he or she displays any of the following:
  • Doesn’t react normally or consistently to sounds. (May be overly sensitive to sounds such as vacuums or hair dryers, yet seem indifferent at other times when someone calls their name.)
  • Mispronounces vowels (i.e. saying “coo” instead of “cow”).
  • Uses one catch-all sound or syllable to name most things (“duh or “duh-duh”).
  • Doesn’t point to common objects in books. Uses a word once and doesn’t use it again frequently.
  • Still says single words only, and not two- or three-word sentences.
  • Answers a question by repeating part of your question or unable to respond appropriately to questions.
