that is truly craptastic timing

i would be inclined (as long as there was no medical reason such as PE or a glaring reason why i might go into labour early) to say go.

will you have finished work by then so you'll be at least more relaxed at home rather than rushing around? is there anyone at the childcare centre who you would trust & be happy to approach with helping out to look after your gorgeous DS if there was a reason you needed to go to hospital? (i would love to offer but i'm worried i may not be the most reliable at that stage!!). do you have a friend that would maybe stay for a night or two to give you a hand or at least keep you company?

ultimately though, i think you need to be really comfortable with your decision - balancing out your concerns & also how your DH will feel if he doesn't go (and how he will feel if he did miss something back here).
