How Many Newborn Diapers Do You Need?

Getting ready for your little one means a lot of diaper changes—probably way more than you’d expect! From choosing the right size to figuring out how many diapers a day a newborn will need, having a game plan can make all the difference and help you feel ready when your baby arrives. Since newborns eat often and go through a lot of diapers in those first weeks, you'll likely be busy with diaper changes, with things levelling off as your baby grows.

We've broken down how many diapers a newborn generally goes through per day, week, and month—and what that looks like over your baby’s first year. You'll also get the scoop on which sizes suit newborns best, how many newborn diapers to buy and have on hand, how long each size typically lasts, and some real-life tips to help you stock up smart—so you can stress less about running out and focus more on those cuddles.

What Size Diapers Do You Need for a Newborn?

Newborn babies generally use the smallest diaper sizes, but every baby is unique, of course. Diaper sizes aren’t about age—they’re all about weight, and they change from brand to brand.

Pampers has got you covered with three categories for the littlest ones, all based on your baby’s weight. That includes three different sizes for preemies and very small infants, plus Size N (newborn) and Size 1 which is now fragrance free!

Newborns’ weights are all over the map. If your little one arrives between 37 and 40 weeks, birth weight usually lands somewhere between 5 lbs (8 oz) and 8 lbs (13 oz). That’s why it’s smart to grab both Size N and Size 1 before your baby shows up. Once you know which fits best, you can stock up and add the right ones to your diaper bag checklist.

Once your little one’s here, you can double-check with our easy Diaper Size and Weight Chart to make sure they always fit just right.

How Many Diapers Does a Newborn Use in a Day?

Wondering “how many diapers a day for a newborn?” It’s actually pretty easy to figure out. Newborns can use up to 10 diapers a day. Of course, every baby is different, so your week-to-week might be a little more or less, but planning for about 70 diapers a week is a good rule of thumb. Plus, you’ll be a diaper-changing pro before you know it! Here’s how to change a diaper if you need a refresher.

Why so many diapers? Newborns pee a lot—sometimes every one to three hours! And when it comes to poop, it’s all over the map at first. After your baby’s first meconium poop, some will go after every single feed. Poop frequency drops off by about 3–4 weeks old, with some little ones going as little as once a week. Be ready for the occasional blowout by having the right size and a healthy extra stash at home.

All these changes mean lots of diapers. Try to swap out the diaper when it’s wet or dirty—not only does it keep your baby comfy, but it helps protect that soft skin from getting irritated or developing diaper rash. That usually works out to a change every two or three hours, give or take.

How Many Diapers per Month?

Planning ahead? You might be asking, "How many diapers does a newborn use in a month? " Since tiny babies eat often and have tiny bladders, you’ll be changing them pretty much constantly at first. So, about 10 a day, or 280 diapers a month, while your baby is a newborn. Just remember, every baby goes at their own pace, so your totals might shift as your little one gets bigger. Over time, they’ll probably use fewer diapers as things get more regular, usually right after feeds.

A handy diaper size and usage chart can help you prep for different stages and plan your stash—and help you figure out how many diapers infants go through a day as they grow.
