well, I've looked at what's available online so far. Since mine is only 2 (3 by matriculation), it's probably a bit easier to find a daycare, than it would be for school. I am not applying to any of the daycares until I know whether I am admitted, and ideally, I would try to find an at-home daycare. Or maybe meet a wife of a fellow student who is staying at home with a child and would like to make extra income

The wait period for some of the good daycares can be quite long, up to 18 months (there's hope for 2nd year in the program lol), but I don't think it's worth stressing about until the admissions decision.
Mine will be 3 too which I guess is easier than finding care for an infant but I have heard that the daycare lists are really long too. The bigger problem is enrolling the 5 year old in school...I called some of the work/life offices at some of the places I was applying to and they seemed to act like that would be a huge big deal and kind of problematic--it sounds like it will be hard to get him into kindergarten than it will for me to get into business school!
