In Wgtn the only stuff they give you are maternity pads (& suprisingly they're nicer thant the supermarket ones so grab as many packs as you can) so you'll need to bring nappies and wipes for the baby as well as a blanket/wrap/swaddle or two.
And some flushable toilet paper wipes (kinda like baby wipes for grownups) - so much nicer and gentler than scratchy hospital 1-ply toilet paper
