Infant's language development

Language development is another important aspect of general development. Language development, especially during the first few years, shows great individual variations. Speech development depends not only on the child's general health and intelligence, but also on his environment, on the speech pattern to which he is accustomed, and on the amount of encouragement and stimulation that he receives. Children differ in their language ability to a considerable degree. Those from poor homes, where clear speech may not be used to the same extent as in more fortunate homes, and those children brought up in an institution, for instance, are usually late in starting to talk and their vocabulary grows slowly. A number of investigators report very great variations in speech development dependent as much on environment as on mental ability. It is, therefore, very necessary to accept any " norms " with great caution. Very intelligent children usually start to talk early and may even be talking before they can walk properly, but usually talking follows walking. Some children, on the other hand, start talking late but then use short sentences rather than single words almost immediately, and thence develop rapidly.


These are the usual stages in language development among normal children during the first two years :-
Early months.—Speech non-existent. Expression by cries of different types, indicating hunger, pain, anger, etc.
5 months.—Babbling and crowing and cooing very much in evidence. Most vowel and consonant sounds distinguishable.
6 months.—Syllables can be detected. " NO " understood. Sign language used.
10 months.—First word spoken.
1 year.—A vocabulary of about 2-3 words. Can imitate sounds and signs.
1 year 6 months.—A vocabulary of about 9 words. One word used to express the meaning of a whole sentence-
2 years.—A vocabulary of about 200 words. Sentences increase in number and complexity.

The process of learning to talk coincides to a considerable extent with the process of learning to walk, that is in the first half of the second year. Speech does not begin to develop rapidly in the average child until walking has been established. After that, the child's vocabulary increases very quickly. Research has shown that the first word uttered by the baby may be one that gives sensuous enjoyment rather than one that expresses an urgent need. It seems that the baby while vocalizing to himself and listening to the sounds around him chances to utter a sound which pleases him and which chances to correspond to a real word. As he repeats this sound, savoring it, as it were, on his tongue, or blowing bubbles in his efforts to make it, he gains ready admiration and encouragement from the adults around him. They may also try to indicate its meaning to him in some way. From then on he may begin to imitate certain sounds and gradually connect them with objects. Vowel sounds are usually the earliest to appear, then the labials and " m " sounds. Gutturals follow soon, while liquid sounds (l's) and aspirates and " th " sounds are usually last.


Adults can help a small child in his early efforts at speech to a considerable extent. First, they should talk to him and sing to him a good deal, so that he can hear the rhythm of speech clearly, and enjoy trying to imitate. Secondly, they should always use a very clear speech pattern and avoid too much baby talk. Onomatopoetic words certainly have their use, and serve when the child cannot pronounce the conventional terms. It is, however, important to discontinue their use early, as this habitual distortion of words is unwise. Such words as puff-puff, bow-wow, etc., and the child's own language terms for very familiar objects will eventually have to be unlearnt. Also, when little children are spoken to in baby language, they frequently resent it and feel they are being talked down to. Sometimes older children continue to use it because in the past they have been praised for it, as a form of showing off to gain an amused audience. On the other hand, some very modern parents insist on using a very difficult grown up vocabulary for the tiny child. When he does begin to talk he struggles with long, rather unfamiliar words, instead of rejoicing in the nursery lingo of Georgie Porgie, Humpty Dumpty, Lucy Locket and See-Saw Margery Daw—delightfully incredible but linguistically satisfying expressions.
