I was similar to Janie. had separate bags.

although for ease and peace of mind (DH is notorious for forgetting crucial things in critical moments lol) i had a backpack full of labour stuff and DDs bag of stuff put INTO my suitcase so that when the time came DH just had to look for the one bag. in the end i was extra relieved as i had to get my friend to drive me in as i went into labour when DH was 3 hours away. it was good to be able (in my slightly panicked state) to just point at the suitcase knowing that it was all there in one piece ITMS.
but this is just a small thing that i found helped us for our frazzled state of minds LOL!

(i also had a list on the fridge for DH...great minds Nae, great minds LOL!)
