We had some suspicious straining going on the other day and he'd stopped running around, I didn't think there was really any need to look, just wait 5 min then do a change, but OH took a peak down the back of the nappy and announced it was currently emerging....
I remember the noises when he was newborn, I was feeding him in the next room whilst OH was in bed and OH could hear clearly. It was depressing when we were both in bed and he fired in the Moses basket straight after a feed, felt I ought to get up again but felt too tired to do so...
And yes, the thought of doing it twice as often is not appealling, but I think it would be worse if you'd potty trained the first one and got past that stage and then had to start all over again!
