## Why Proper Diaper Sizing Matters
A diaper that is too tight causes friction rashes and restricted circulation, while one that is too loose leads to messy leaks and skin exposure to prolonged dampness.
### How to Know It's Time to Size Up
1. **Red Waistband Marks:** Red pressure indentations around your baby's thighs or tummy after removing the diaper.
2. **Frequent Side Leaks:** Blowouts or urine escaping along the leg ruffles.
3. **Tab Position:** Fastening tabs reach the far edges rather than resting comfortably in the middle.
> 💡 **Doctor's Advice:** In Bangladesh's tropical humidity, consider breathable diapers with cotton-soft micro-porous backsheets that allow heat to dissipate while locking fluids inside the core.
