Expert Note
The number of diapers matters, but the routine depends on more than size math. Wipes, rash care, and disposal are what make the diaper station work day after day once the baby is home.
That is also why size distribution matters so much. A great diaper plan is not just about total volume, it is about buying the sizes and support items that stay useful as the baby grows.
