Size progression timeline (newborn → toddler)
The average baby goes through ~7,500-8,000 diapers from birth to potty training (3 years). Cumulative cost: $750-$2,000 depending on brand. Cuddle-Kin's bamboo subscription locks in the $0.097/diaper rate across all sizes.
Summer vs winter diaper count
Hot weather (80°F+) bumps changes up by 2-3/day vs winter baseline due to faster sweat + skin acidity breakdown. Summer newborns: ~420 diapers/month vs winter newborns: ~330. Bamboo's 30-40% better breathability makes summer changes less urgent.
Should you stockpile diapers?
Yes — but with limits. Stockpile 2-3 months of CURRENT size + 1-2 months of NEXT size. Don't stockpile beyond that — babies grow unpredictably. Cuddle-Kin's monthly subscription auto-rotates sizes as baby grows, eliminating stockpile waste.
