Another flash news for people who haven't had kids in daycare for a while - pricing for daycare means that for the first kid the mom could work and come ahead money wise. Second kid is about neutral (depending on location and salary, in some cases the mom comes ahead money wise, in other case she does not). Daycare pricing made us decide to have 1 kid - if we had 2 kids in daycare my wife would have been better off staying at home (which we could not afford and she did not want to do anyway).
Access to contraceptives make a significant difference as well.
