Important: Many parents are unaware that leaks and blowouts often arise from using the wrong diaper size. The My Perfect Fit tool is designed to help you address this issue effectively.
Benefits of using My Perfect Fit sizing tool:
- Reduces the likelihood of leaks and blowouts.
- Ensures optimal comfort for your baby.
- Helps you choose the most suitable Pampers product for your baby's needs.
Tip: Regularly re-check your baby's size, especially during growth spurts, to ensure a proper fit.
To help prevent leaks, follow these steps to check your baby's diaper fit:
- Choose the right style: Consider whether taped diapers or diaper pants are best based on your baby's mobility.
- Check the weight range: Ensure your baby is within the correct weight range for the diaper size
- Ensure a snug fit:
- The diaper should fit snugly around the waist, thighs, and bottom.
- No gaps should be present.
- For taped diapers, secure the tapes in the center of the picture strip.
- Gently run your fingers along the inner leg cuffs to ensure they're not tucked in.
- Consider sizing up: If the diaper is consistently full or leaking, you may need to move up a size for more absorbency.
Important: A leaking diaper may indicate that your baby needs a more absorbent diaper or a different size and fit.
