yeah, some nice bath stuffs to ease the extreme pain of childbirth would probably be much appreciated as well. Just wait until your GF/Wife/etc. gets pregnant.. Just HEARING about this stuff makes me cringe, and mad/sad/scared at the same time! Things like knifes and scissors and other such objects that should never be "down there" ever.
My first will be born in about a week at most (fiancee is currently in "active" labor as I speak.. she's not the most fun person to be around right now.

Although this has lasted for a few days and we keep getting sent back from the hospital. To the mothers in here, she's at a 4 right now.), so I've been through all the shower stuff allready.
The baby stuff is appreciated just as much by the dad! Believe me! This stuff is expensive as hell nowadays.
I've seen both unisex and the more traditional womens-only parties. Ask one of her friends which it is.
