The objective here is to analyze the effect of having children on women's share in the economically active population, observing the temporal evolution of this effect during the 1990s. In addition, based on the fact that each child may exert a different effect on a mother's decision to work or not, the effect of the first, the second and the third (or more) children on this woman's share in the economically active population were estimated. In general the findings suggest that, regardless of order of birth, children reduce the likelihood of women to participate in the labor market. Also, during the 1990s and the decade of 2000 the negative effect of the first and second children on women's share in the labor market fell in impact, whereas the effect of a third child took on some importance.
