I'd pack an emergency bag for DH to bring in in case what you have isn't enough. You know - a bag with a few more undies, some extra pads, another set of pjs or wahtever.
The only reason I say put them aside is its alot easier to say to them - can you grab me the PJs I've put aside in this bag and bring them in, then say can you bring me the ones that have stripes/spots/flowers. You know what I mean.
Also I think that undies would be a good thing to put aside for them. Imagine asking for a few pairs of old knickers, and them bringing in your fav lacy ones, or something that couldn't hold a pad in place.

But I think a fair bit of it is unneccessary.
