I just opened one of tena lady pants up - they look like adult nappies! They seem quite soft so I don't think they'd rustle.
I'm not sure if sanitary pads would work, I guess it depends on the amount of bleeding? I read some people were doubling up
and also that some midwifes look at the used pads to see how much blood there is?
Kotex nights sanitary pads seem quite popular, but I think the thick ones. TBH it's probably best if someone who has done this before comments on the best things to use, as I've only read this stuff!
Other stuff in my bag of horrors goodie bag: postpartum bath herbs, biofreeze pain reliving spray, vitamin D, magnesium oil, raspberry leaf tablets, coral calcium tablets and witch hazel bath spray. Think I'll be spending some time on google!
