If you are a new parent or soon to be, you may be wondering how many diapers to stock and which type to buy.
Some experts believe that babies go through up to 2,000 to 3,000 diapers in their first year of life! However, assuming you’ve opted for disposable rather than washable cloth diapers, figuring out how many of each size and type to buy can leave even experienced parents scratching their heads.
That’s why we’ve put together a guide to help you estimate how many diapers of each size to buy (or add to your registry) before your baby arrives and best diapers to buy for each stage of development.
Newborn nappies are suitable for babies around 7lbs to 10lbs, so unless your child was born prematurely (size S nappies can also be easily found) or particularly large at birth, it will be the diaper size you’ll probably want to have on hand when you first bring your child home. The best newborn diapers also offer a cutout for the umbilical cord area to prevent chafing and irritation in this sensitive area.
How many you will need of this diaper size largely depends on your child’s birth weight. Although the average full-term baby weighs approximately 7 1/2 pounds at birth, your own baby could be smaller or larger than the norm, depending on a wide range of factors that influence birth weight. However, as a general rule, most newborns gain about 2 lbs. in the first month of life.
So if your child is of average birth weight and changes around eight to 12 diapers a day, that would mean you would need around 240 to 360 newborn diapers in total. Keep in mind that if your child is over 7 1/2 pounds at birth you will need fewer diapers or if they were born smaller than average you may need even more .
Diapers size 1
Although some babies spend only a short time in newborn diapers, most babies will spend at least several months in size 1 diapers, as these weigh between 8 and 14 pounds. So if you want to buy in bulk or put diapers on your registry for pair with a diaper bagsize 1 diapers are a great choice for this reason.
While the newborn stage is a time of rapid growth, most babies tend to slow down their weight gain after the first month, averaging around 5-7 ounces per week. So, as a rule of thumb, 650-1000 nappies will cover about three months at this point. If you haven’t bought one yet, a great diaper bag — or diaper backpack – will certainly be useful at this stage.
Diapers size 2
Once your baby reaches 12 to 18 pounds, he can move on to size 2 diapers. One of the benefits of reaching this stage is that your child will hopefully need fewer diaper changes as he begins take more milk or formula with each meal. . This may mean that you only need eight or nine diaper changes a day instead of needing up to 12 a day as before.
Assuming your baby will spend three months at this size, 650-750 nappies is a rough estimate of how many you might need to get by.
Diapers size 3
By the time your child is ready for size 3 diapers, they will weigh between 16 and 28 pounds. Generally, babies would tend to stay in size 3 for the longest period of time – about six months according to some estimates. Assuming six or seven diaper changes a day, that could mean you might need 1,000 to 12,000 size 3 diapers before moving on.
Additionally, once your child starts sleeping through the night (usually around six months of age), you can also consider adding overnight diapers to your stash. These are thicker, more absorbent diapers that help keep a baby drier for longer periods of time and prevent leaks and rashes that might otherwise wake your child.
Diapers size 4
As your child approaches 2 years of age, you may begin to consider potty training, or your toddler may be ready to learn diapers that allow him more independence. Alternatively, your child may not yet be ready for all this freedom and may need to upgrade to size 4 diapers once they reach a weight of between 22 and 37 pounds. Since each child’s needs may be unique, you may want to hold off on stocking up on diapers of this size until your child is closer to this stage and you have a better idea of their diaper needs.
Once you’ve decided they’re ready for workout layers, like Pull-Ups or Easy Ups, you’ll find the sizing is easier to understand. At this point the sizes come in a range that aligns with what you would buy their pants in, so 2T-3T or 4T-5T, for example. These diapers are often sold in smaller quantities than regular diapers, but hopefully you’ll only need them overnight rather than all day.
Finally, if you’re taking your little one to the pool and don’t want them to just pee in the water while swimming, get a pack of swim nappies, which won’t swell or get heavy. like regular diapers. You can get disposable or reusable ones in different designs. Swim diaper sizing patterns can vary by brand, but generally align with numbered sizes that are your baby’s usual size.
However, Pampers uses lettered sizes for its line of Splashers swim diapers, in which S covers 13-24 pounds, M covers 20-33 pounds, and L covers 31+ pounds.
