Gave birth at WHC in January (although not Kaiser). We took everything we could get our hands on - numbing spray (I actually asked for extra of this cause I loved it), pads, those witch hazel things, peri bottles, cleansing wipes, mesh undies, diapers, vaseline, etc, etc. Started packing it up the day before so they would refill and we could take more. No additional charges, just my $500 hospital co-pay.
