#AskTheExpert hii, my baby is of 2 year and 10 month old baby boy is not clearly speaking some words ?any reason behind it?

A. By 24 months (two years), 50 to 75% of speech should be intelligible to familiar people. By 36 months (three years), 75 to 100% of speech should be intelligible to familiar people. By four years of age, a child should usually be understood, including by people who are unfamiliar to them.
