FAQ
How do I know what diaper size my baby needs?
Go by weight, not age. Newborn: <10 lbs, Size 1: 8-14 lbs, Size 2: 12-18 lbs, Size 3: 16-28 lbs, Size 4: 22-37 lbs, Size 5: 27+ lbs, Size 6: 35+ lbs. Signs of wrong size: blowouts, red marks on thighs/waist, or leaks. Size up when reaching upper weight limit.
Should I stock up on newborn diapers?
Buy 1-2 packs max. Babies outgrow newborn size in 2-4 weeks (some never fit them!). Focus on Size 1 (most babies wear 1-3 months) and Size 2 (3-6 months). Buy in bulk once you know baby's brand preference and growth rate.
Do diaper brands fit differently?
Yes! Pampers run narrow/snug (good for skinny babies), Huggies wider (chunky thighs), Honest Company runs small (size up), Target Up&Up similar to Pampers. Try sample packs to find best fit. Even within brands, Swaddlers vs Cruisers fit differently.
