There might be something wrong with your baby, or maybe you have babies? When I had my first child I naively thought they shit all the time (like all day - I was an idiot). In reality, they typically shit once a day (like us!), so maybe 5 total diapers, but not all are shit filled.

Site note: We used cloth diapers for both our children and urine (that's been sitting in a diaper pale) is by far worse than shit smell.
