What Diaper Sizes Should I Buy? A Guide to Choosing the Right Diaper Sizes for Your Baby

As you wait for your newborn to arrive, you are filled with anticipation and nervousness. One of the many thoughts that may be running through your mind is, "What diaper sizes should I buy?" The ideal diaper size for your baby depends on their weight and individual needs.  

Choosing the proper diaper size is important for your baby's comfort and well-being. Swaddle Tote is here to help you through the process, giving you the knowledge you need to make informed decisions and create a smooth diapering experience for both you and your child.

Understanding Diaper Sizes: What You Need to Know

Diaper sizes are generally based on your baby’s weight, and they come in a range of options to accommodate their growth. Here's a quick rundown of the typical diaper sizes and what to expect:

Newborn

The Newborn size is intended for the smallest babies, which can weigh up to 10 pounds (4.5 kg). It is typically designed with an umbilical chord cutout or a lower front rise to match the healing umbilical cord stump. It provides an accurate fit and prevents leaks while softening the baby's sensitive skin.

Size 1

Size 1 is normally appropriate for babies weighing between 8 and 14 pounds (3.6-6.4 kg). This size is slightly larger than the Newborn size and is excellent for babies who have outgrown the smallest size but still need a tight, snug fit. It is a wonderful combination of absorbency and comfort for babies who are gaining weight while remaining relatively small.

Size 2

Size 2 is typically suited for babies weighing 12 to 18 pounds (5.4 to 8.2 kg). The following size is suitable for growing babies who require a bit more space. It is ideal for babies who are becoming more active and may require a diaper that may handle their increased movement. Size 2 diapers often have adjustable hooks to ensure a secure fit without being too tight.

Size 3

Size 3 is designed for babies weighing between 16 and 28 pounds (7.3 to 12.7 kg). Size 3 is suitable for toddlers who are starting to investigate their surroundings more actively. The larger size gives more coverage and absorbency to allow for longer intervals between changes, which is useful as babies start to sleep for longer periods of time or stay active throughout the day.

Size 4

Size 4 is normally appropriate for children weighing between 22 and 37 pounds (10-16.8 kg). When toddlers enter the toddler stage, they require diapers that can accommodate their increased mobility and growing bodies. Size 4 diapers provide enough absorbency and covering, which is especially important for active toddlers who may run and explore.

Size 5

Size 5 is appropriate for older toddlers weighing 27 pounds (12.2 kg) or more. Children that require a larger fit due to their size or who require more absorbency should choose this size. Size 5 diapers are appropriate for children who are about to start potty training but still require effective leak protection.

Size 6

Size 6 is the largest diaper size offered, fitting children weighing 35 pounds (15.9 kg) or more. Older kids who outgrow their former sizes and prefer a bigger, more absorbent diaper are the target audience for this size. Size 6 provides maximum coverage and is intended to handle bigger amounts of fluids, making it appropriate for heavier and more active children.

How Many Diapers Should You Buy in Each Size?

How Many Diapers Should You Buy in Each Size?

It's important to plan and stock up on the right amount of diapers to avoid running out. Here’s a general guideline on how many diapers you might need:

  • Newborn Size: 2-3 packs
  • Size 1: 3-4 packs
  • Size 2: 4-5 packs
  • Size 3 and beyond: 4-6 packs each size

On average, newborns use approximately eight to twelve diapers per day. However, every baby is unique, so you'll need to observe and adjust your expectations as you learn your baby’s specific needs. To save money, consider buying diapers in bulk. 

Typically, "boxes" contain more diapers than "packs"—for instance, a size 1 pack generally has around 40 diapers, whereas a size 1 box contains about 164 diapers. While boxes often offer a lower price per diaper, it's important to do your research and plan your budget accordingly.

Tips about Efficient Storing

Tips about Efficient Storing

  • Organize by Size: To make things easier and more accessible, segregate diapers by size and store them in separate compartments of your diaper bag or storage place. This strategy allows you to easily select the appropriate size without having to look through a mixed pile. If you're using a diaper bag, consider utilizing separate compartments or pouches for each size. At home, you may use labeled bins or drawers to make it easier to find the correct size.
  • Monitor Growth: Babies develop quickly, so keep an eye on their size and modify your diaper supply accordingly. Check your baby's weight regularly and avoid accumulating diapers that they have outgrown. Conversely, ensure that you have enough of the following size up to avoid running out when it is required. Some parents find it useful to keep a growth chart or track milestones to determine when it is time to transfer sizes.
  • Be Prepared: Always keep a few extra diapers on hand to accommodate any unexpected events, such as lengthier outings or a delay going to the shop. Keeping a little stock of each diaper size on hand guarantees that you won't be caught off guard if your kid requires a change and you're running low on supplies. It's also a good idea to keep a few extra diapers in your car or at a grandparent's house to avoid diaper emergencies while away from home.

Choosing the right diaper size is essential for your baby's comfort and well-being. By understanding the different diaper sizes and considering your baby's individual needs, you can make informed decisions and ensure a smooth diapering experience.
