Crunch the Numbers
Does it make good financial sense for you to continue working? While instinct might tell you that two working parents will always yield a greater net profit than one, once you factor in childcare, that's not always the case.
Figure out a realistic childcare budget, and remember to base your own income off of your take-home pay as opposed to your salary. Also take into consideration the cost of commuting and any other expenses that you may incur in a daily work (or SAHM) day.
