I did that when I had my 9lb 1/2 oz.son...afer 30 hours...I stared on the clock like focused right on it...natural birth (as the epidural didn't take) Anyway it was quite a traumatic delivery he was stuck and in an emergency vacuum extracted him....I guess this was traumatic enough...when I think of my delivery....I remember that damn clock......I didn't notice that I had done this but I remember shoes...when I had the rape kit done...
