A nowadays (avoiding the loaded term “modern”) wife would surely know how to present her position and in any normal family, the decision would be mutual, with each side appreciating the arguments of the other. As I mentioned, the women are pretty likely to be in the loop. Just compare specificity of imamother replies with the blabber at this site :). If parents are not able to come to a joint opinion, they would be better off asking for an advice or a shailah to figure out how to have a joint opinion on important issues.
