Actually, I've had that happen numerous times.
I had a LO last year who never had stinky poops. I felt really bad about it; she was a red head with very sensitive skin, to boot. Until one day GMA complained about it...whew!
I think it is the antibiotics in your case. Very common..the diahrrea and rash. It happens. Don't apologize. You know you didn't ignore a dirty diaper willfully.
