This paper analyses the behavioural effects of infant and child mortality on birth intervals in Kenya. Analysing the behavioural effects of infant and child mortality on fertility independent of its biological effects has been considered a difficult task. In this paper, a procedure for analysing these effects separately is developed and applied to the 1989 Kenya Demographic and Health Survey (KDHS) data. The results of the analysis suggests that women in Kenya adopt various strategies such as curtailing the duration of breastfeeding, increasing frequency of coitus, and to a lesser extent use of contraception in order to replace infant or children who have died or to insure against those who are likely to die. These findings suggest the existence of behavioural effects of infant and child mortality on fertility in Kenya
