A. call the doctor for speech therapy if your child's speech is harder to understand than expected for their age: Parents and regular caregivers should understand about 50% of a child's speech at 2 years and 75% of it at 3 years. By 4 years old, a child should be mostly understood, even by people who don't know the child.
