Babyluv, I'm not sure what the Womama is but it sounds like what I wore, except more fancy! My sister and I have both worn the same nightie - its just a simple one from Bras n Things but it buttons all the way down so you can rip it open easily for access to your chest post birth. For my first I had it on and done up, but for my second I basically arrived at the birth suites in my shorts and tshirt, stripped off for the shower then when I came out to push DH sort of draped it over my shoulders, more so I wouldn't get cold!

It was about mid-thigh length. Just a Short Stories brand so not expensive or fancy but it did the job. It has also washed up really well and I'll be able to wear it again if I have a third...

Oh and the TENS machines are great.
