I had my clothes on when i got to the delivery suite (just mat pants and a top) but stripped off straight away to get in the bath. I had to get out when we saw there was meconium in my waters and then i just asked to put a hospital gown on, i didn't want all that stuff getting on my clothes or new nightie!

I'm a bit of a prude usually and swore i would stay clothed but ended up naked most of the time and preferred it.
