Ask him before he induces you, will he guarantee his attendance! If you wanting to be induced is only for his attendance and he doesn't make it because of *whatever* how would you feel? Ripped off? Sad? Don't care?

I've had my OB miss one of mine as have several other BB members. It's why they work in teams because it's impossible for them to be in two places at once and if it comes to it that someone else is giving birth at the same time as you, one of you will miss out!
