About Diaper Cost & Usage
The number of diaper changes times the cost per unit gives a daily spend that scales to a month and across the months until potty training. Newborns need more changes per day, while older toddlers use fewer diapers but bigger sizes. Diapers are a steady, predictable expense, so knowing the monthly figure lets families compare cloth versus disposable and budget without surprises.
