Would any of the moisturising type oils work, or would they absorb too well? Like Bio Oil, or Palmer's, OR actually I have a Body Shop Spray one somewhere here that I really like but can't find...think it's Papaya smell?

Otherwise, I'd go with a basic carrier oil like sweet almond. You could even pre-mix it with a smell that you really like for labour if you want (for example, I mix pretty much everything with Eucalyptus oil...I think I'm addicted...I'd have it in my food if I thought it'd taste good. ).

Ooer 33 days to go, all the best Astrid!

ETA: Afterthought - if you labour in the shower, that's another good way for dh not to chafe your skin - just make sure he's packed his swimmers or a change of clothes!
