Document Summary
Children make vegetative sounds from birth they cry, burp, and make sucking noises around 6 weeks they start cooing. 16 weeks 6 months they engage in vocal play: involves making speech-like sounds vowels emerge before consonants. 6-9 months infants start babbling: presence of true syllables (consonants + vowels), often repeated. 9 months infant starts noticing that particular strings of sounds co-occur with particular situations. 10-11 months infants start producing their first words: the single words are sometimes thought of as forming single-word. Before children produce utterances that are grammatically correct by adult standards, they produce what"s called telegraphic speech contains a number of words but with many grammatical elements absent. As grammatical elements appear, they do so in a relatively fixed order for any particular language. 2 yrs 6 mths, the child produces increasingly complex sentences. It"s hard to carry out controlled experiments on large numbers of young children to examine their linguistic development.
