Not all kids start talking at the same time, but it’s important to identify those who are delayed. That’s because delayed speech in toddlers is a risk factor for language and reading difficulties later, and can sometimes be a sign of autism or mental retardation.UniversityofNew Mexicodevelopmental psychologist Philip Dale says for American English, if a child isn’t speaking 25 distinct words by the age of 2, it could be a sign of a delay. But he adds that screening criteria for late talkers depend on the culture.

PHILIP DALE (UniversityofNew Mexico):

HIRSHON:
