How can you tell if my child has problem with articulation (pronunciation and talking)?

If a child has difficulties with articulation they might:

• Become overly frustrated when communicating with others.
• Produce speech that is difficult to understand even for familiar listeners.
• Have difficulty linking together more than one or two sounds.
• Tend to use only vowel sounds (very open mouthed noises).
• Produce speech that is unclear alongside dribbling and messy eating skills.
• Produces speech that is less clear than other children of the same age.
• Produce an interdental lisp (e.g. tongue protruding between the teeth when saying a /s/ or /z/ sound) if over the ages of 3.5 – 4 years.
• Be school aged and still having difficulty saying several sounds.
