I'd be encouraging him not to go. Lots of women with first bubs do go early. Someone I work with knows someone who had her bub 3 weeks early and had a 1 hour labour which resulted in bubs being born in the hospital carpark. Yes it was her first bub. Then again, her husband still missed the birth as he was in the hospital trying to get some help out to the car, so there's never any guarantee that they'll get there even if they are local when labour starts.

If he does have to go do like the others have said and have a good back up plan with someone you trust organised to come along and support you. No matter what happens you will cope - how does the song go - I am strong, I am invincible, I am woman.
