The phenomenon of sibling rivalry and its impacts encourage the need for efforts to prevent it. The purpose of the study was to describe the characteristics of pregnant women, the level of knowledge of pregnant women about sibling rivalry, the level of behaviour of pregnant women in preventing sibling rivalry, and analyze the relationship between knowledge of pregnant women and behaviour in preventing sibling rivalry. The research method used a quantitative approach with a correlational type. The population was pregnant women who had children aged a maximum of 3 years and checked their pregnancy at the Kagok Semarang Health Center. The number of samples was 63 people. The side technique used total sampling. Data were obtained using a questionnaire and then analyzed with descriptive statistics and the Fisher exact test, a statistical test used to determine if there are nonrandom associations between two categorical variables. The results of the study were the characteristics of pregnant women, the majority aged 20-35 years, parity less than or equal to 3 births, high school education, working and family income according to the UMR. The level of knowledge of pregnant women about sibling rivalry tended to be less good, and the level of behaviour of pregnant women in preventing sibling rivalry tended to be quite good. There was a very significant relationship between knowledge of pregnant women and behaviour in preventing sibling rivalry (chi-square = 49.810 and p <0.05). The conclusion is that pregnant women's knowledge is a factor in preventing sibling rivalry behaviour.
