hello sir, My son is 6 years old but his pronunciation is not clear for some sounds like r, dha, th, n some more. so what can be done

A. If your child is 6 years old and still demonstrating speech errors, make an appointment to speak with a speech-language pathologist, also known as a speech therapist. The speech therapist can evaluate your child and recommend treatment if it's needed. The earlier you reach out, the better.
