I took it with two infants. I honestly can't say which would be worse - although my score was not terrible, considering how little prep I did, and how little sleep I was getting at the time (and the fact I was going through a divorce - eek!). I know some people with blood sugar issues get to bring snacks, so it perhaps you could get a special dispensation to have something on hand to eat? It really goes by so fast - - but maybe not if you're dying of hunger and have a 6 pound baby tap dancing on your bladder;-).
Dotlyn, I don't want to hijack the thread, but I share your mixed feelings about giving up the SAHM thing. I will find out this week if LSAC is going to leave my GPA in good shape for UC-Davis, and if it does - I'll be frantically trying to figure out if I can afford good options for the twins (not to mention if I'll be able to handle going cold-turkey on the all-day mom thing!). Good luck!
