it is generally suggested you use only warm water on a new born baby anyway...
...i agree, at such a young age they seriously do not need more than warm water.....save it for when baby gets a bit older.

Thongs ??? - ive always taken thongs and worn them in the shower. I shudder to think whats been down that shower drain ........

Personally - i would ditch the labour bag, but thats me....

Good luck !
