Development of Language
Children vary naturally, and according to their environment, in the rate of development in use of language. Any effort to hasten the process of talking or vocabulary during the first four or five years is an artificial forcing that is more likely to retard development. The following represents all that should be expected of a normal child.
First six months: crying, gesture language
Second six months: babbling, imitation of sounds, gesture language
One year: three to ten words
One to two years: vocabulary of 100 to 500 words; two-word sentences
Two to three years: 500 to 1500 new words; begins use of pronouns
