Wow - that is awesome! I tried for a waterbirth at home with number 1 but my labour went on for days and days..... so jealous- I hated hospital and felt so at ease at home in my own space.
Truely - I think the heavens were looking out for you. If you'd made it to the hospital earlier, there's a BIG chance you would have ended up with a c/section due to the breech factor, and consequently all the intervention and risks that come with it (epidural, antibiotics, etc).
It just proves what a woman's body is capable of if she allows mother nature to take charge without fear. You are amazing. Well done!
Just don't let DP go to work this time around coz it will probably happen even quicker!!

Oh - and I would have loved to have heard the reactions of the hospital staff when they found out you gave birth naturally to baby feet-first on the bathroom floor - classic!!
