The average baby will use how many disposable diapers before they are toilet trained?

I am not sure exactly how many diapers are used exactly, because it depends whetheryou toilet train your child at 2, or wait 'till they are three, or even 4. But the average baby uses 4.2 trees in diapers which is alot! And if you think about how many babies there are in the world, babies might as well cut down a tree and crap on it. No wonder we have probs with global warming!
