What Size Diapers Are For What Age?

When it comes to choosing the right diaper size for your baby, it’s important to consider their weight and age to ensure a comfortable fit and effective leak protection. Different diaper brands may have slight variations in sizing, but generally, there are standard size ranges based on weight that can help guide you in selecting the appropriate diaper for your little one.

Newborn Diapers

For newborns weighing less than 10 pounds at birth, diaper sizes can vary to ensure a snug and secure fit. The Pampers newborn size, for instance, is ideal for infants who fall within this weight range but do not require special premature sizing. These diapers are specially designed to be gentle on delicate newborn skin while providing reliable leak protection.

Size 1 Diapers

Once your baby outgrows the newborn size, they may transition to size 1 diapers, which are typically designed for babies weighing between 8 and 14 pounds. These diapers are slightly larger than newborn sizes and offer a comfortable fit for infants who have started to gain more weight and size. Size 1 diapers are great for babies who are still in the early stages of development.

Size 2 Diapers

As your baby continues to grow, they may graduate to size 2 diapers, which are suitable for infants weighing between 12 and 18 pounds. These diapers offer a bit more room for movement and provide ample coverage for babies who are becoming more active and mobile. Size 2 diapers are perfect for babies who are transitioning from the newborn phase.

Size 3 Diapers

For babies weighing between 16 and 28 pounds, size 3 diapers are a popular choice. These diapers are designed to accommodate larger babies who need extra absorbency and coverage. Size 3 diapers are great for babies who are starting to sit up and crawl, as they provide a secure fit that moves with your little one.

Size 4 Diapers

Once your baby reaches the 22-37 pound weight range, size 4 diapers may be the right option for them. These diapers offer enhanced leak protection and are perfect for active toddlers who are always on the go. Size 4 diapers provide a comfortable and flexible fit that allows your baby to move freely while staying dry and comfortable.

Size 5 Diapers

For toddlers weighing between 27 and 35 pounds, size 5 diapers are a suitable choice. These diapers are designed to keep up with active toddlers who may be potty training or transitioning to independent movement. Size 5 diapers offer superior leak protection and a secure fit that allows your little one to explore the world without any worries.

Size 6 Diapers

Size 6 diapers are typically designed for toddlers who weigh over 35 pounds. These diapers offer maximum absorbency and coverage, making them ideal for older toddlers who are still in diapers. Size 6 diapers provide a comfortable fit and reliable leak protection, ensuring that your child stays dry and comfortable throughout the day and night.
