I'd say close to 95% cloth. We use cloth at night and on outings now. The only time I use sposies is when I'm treating a bad rash. Unfortunately DS is super sensitive, so that happens about once or twice a month. He's usually only in sposies for one day, so averaging two days every thirty gives us about 6-7% of the time in sposies. I'll say 95% cloth to err on the side of caution.
I will admit to taking breaks from cloth if I am very, very sick, or if DS has a stomach virus or something and turns into a poop machine. Thankfully that happens rarely, once a year maybe, so I figure it's statistically insignificant (yep I'm a huge nerd).
