Although much attention has been devoted to lexical, grammatical, and
semantic aspects of child-directed speech, less is known about its pra
gmatics. This paper describes a longitudinal study of the communicativ
e intents used by parents in interaction with their 14-, 20-, and 32-m
onth-olds (n = 52). With 14-month-olds, parents used a small core set
of communicative intents. This set grew in size and sophistication wit
h increasing child age. Comparison with children's intents showed that
some commonly used parental communicative intents were rare in childr
en's language at all three ages. As children grew older, parental use
of directive intents declined and child-centered acts increased. These
findings suggest that child-directed parental speech is simplified pr
agmatically as well as grammatically and semantically.
