Diaper Fit Tips
- The waistband should fit snugly but allow two fingers between the diaper and baby's belly.
- Leg cuffs should be pulled out (not tucked in) to prevent leaks.
- If you see red marks on baby's thighs or waist, it's time to size up.
- Frequent blowouts usually mean it's time for the next size, not a tighter fit.
- If the diaper looks saggy or droopy, you may have sized up too soon.
- Overnight diapers are one size up from daytime — extra absorbency for longer stretches.
