Diapers per Day vs Baby Age
Diaper Usage by Age
Newborns use the most diapers, with usage declining as babies grow.
Estimation
Daily Diapers = max(12 - Age(months) x 0.25, 5)
Newborns (0-1 month): 10-12 diapers/day. Infants (1-6 months): 8-10. Older babies (6-12 months): 6-8. Toddlers (12-36 months): 5-7. Most children are potty trained between 2-3 years.
Example Calculation
A 6-month-old baby using diapers at $0.28 each.
- 01Daily diapers = max(12 - 6 x 0.25, 5) = max(10.5, 5) = 10.5, rounded to 11
- 02Monthly = 11 x 30 = 330 diapers
- 03Monthly cost = 330 x $0.28 = $92.40
- 04Annual cost = 11 x 365 x $0.28 = $1,124
