Is there anything missing out of my hospital bag for the birth?

One thing that hasn't been mentioned is make sure to pack a comfortable sweater for your husband. They keep the delivery rooms fairly cool for the labouring mamas. Also, try to make sure to pack a sandwhich or something for your husband (I mean remind him to pack one ;)). That way he doesn't have to leave to get something to eat if you're having a very long labour. Also, bring a hot water bottle, mine provided me some relief. I brought crocs to wear because there's lots of . . .um. . . stuff that will get on your feet, so you'll want shoes you can rinse easily. There will definitely be things you won't use, but you won't really know for sure what you need until you go through it.
