Frequently asked questions about diaper
Cloth vs disposable diapers — which is better?
Disposables: convenience, no laundry, easier for travel + daycare. Save 2-3 hours weekly vs cloth. Cloth: $1,500+ savings over diaper years, eco-friendly, fewer skin issues. Many parents use combination — cloth at home, disposables for outings + overnight. Many daycare centers won't accept cloth.

Newborn (NB) — first 2-6 weeks, many babies skip entirely. Size 1 (8-14 lbs) — 4-6 weeks to 4 months. Size 2 (12-18 lbs) — 4-7 months. Size 3 (16-28 lbs) — 7-14 months. Size 4 (22-37 lbs) — 14 months-2 years. Buy 1 pack at a time of newborn — they outgrow fast. Stock up on size 3+.

How do I tell if a diaper is too small?
Red marks on baby's hips/thighs. Diaper rides up the front. Frequent leaks (overflow). Diaper covers less than 80% of bum. When sizing up: change brand or size — overlap brands at transition. Don't go too big either — leaks happen with poor fit at any size.
What diapers are best for nighttime?
Pampers Baby-Dry Overnight (most absorbent). Sleepy Cat (premium overnight). Cloth diapers with nighttime inserts (heavy hemp/bamboo absorbers). Use one size larger for overnight if leaks are frequent. Apply Aquaphor diaper rash cream as prevention before bed. Some parents skip overnight changes for older babies (12+ months).
