Awaiting the arrival of a newborn is a joyful journey—filled with excitement, planning, and the desire to prepare the very best for their special day. From tiny outfits and essentials for mom to diapers and daily care items, every detail matters. And for new parents, diapers are a big topic: “How many should we buy?” and “How many diapers does a newborn use each day?” In this chapter, we share a practical newborn diaper guide to help you feel confident, prepared, and ready to welcome your little one with ease.
🍼 Quick Newborn Diaper Guide
How Many Diapers Does the Average Newborn Use a Day?
Newborns typically go through 8-12 diapers per day, with the first week possibly reaching 12-14 diapers daily.
How Many Diapers to Buy Before a Baby Comes?
For your newborn, 200 NB diapers is a perfect starting point—this is roughly 9–10 packs of Aiwibi NB (22 pcs per pack). To stay ahead of growth spurts, keep 1 pack of Size P (Size 1) diapers ready for a smooth transition around week 3–4.
How Many Diapers Does the Average Newborn Use a Day?
Newborns (0-1 month) typically fly through 8-12 diapers per day—and in the first week? Buckle up! Those early days can mean 12-14 diapers daily as they adjust to feeding rhythms.
- Weekly estimate: About 70-84 diapers
- Monthly estimate: 300-360 diapers in the first month alone
Age-by-Age Diaper Needs: Watching Your Baby Grow
As your newborn blossoms into a squishy infant, their diaper habits will shift. Here is the sweet, simple breakdown:
| Age Range | Daily Diapers | Monthly Estimate | Sweet Note for You |
|---|---|---|---|
| Newborn (0-1 month) | 8-12 | 300-360 | Those tiny NB diapers won’t fit forever—savor these moments! |
| 1-3 months | 6-8 | 180-240 | Diaper changes are still a cozy bonding ritual. |
| 3-6 months | 5-7 | 150-210 | More time for giggles and play! |
| 6-12 months | 4-6 | 120-180 | Toddlerhood is near; diapers are your trusty sidekick. |
By their first birthday, your little one will have used roughly 2,500-3,500 diapers!
Why Do Newborns Go Through So Many Diapers?
- Tiny bladders: Newborns’ bladders are about the size of a cherry, so they pee every 1-3 hours.
- Frequent feedings: Food goes in... and well, you know the rest. It’s nature’s way of keeping things moving!
- Soft, frequent poops: Breastfed babies often have 3-5 soft poops a day, while formula-fed babies have fewer but more substantial ones.
What Affects Diaper Usage?
Every Baby Is Unique! Just like every baby has their own little personality, their diaper habits are one-of-a-kind too. Here are the sweet, relatable factors that might tweak your numbers:
1. Age & Weight (Tiny = More Changes!)
Newborns under 10 lbs (4.5 kg) need extra changes—their bodies are still learning the ropes! Premature or smaller babies might use 20% more diapers, and that’s totally okay. Every tiny step (and tiny diaper) is a win.
2. Feeding Style (Breast vs. Formula)
Breastfed babies: Soft, frequent poops mean more changes—breast milk is easy to digest and keeps their systems active . But hey, that liquid gold is fueling their growth—worth every diaper!
Formula-fed babies: Fewer poops, but they’re thicker (hello, “poop explosions” sometimes!). Either way, you’re doing an amazing job feeding your baby.
3. Diaper Quality (Soft = Happy, Absorbent = Less Changes!)
High-absorbency diapers (with quality polymer cores ) can cut down on changes slightly—they lock in wetness so your baby stays cozy longer.
How Often Should You Change a Newborn’s Diaper?
There’s no “perfect” schedule—just what works for your baby. But here’s our gentle, parent-approved advice:
- Change every 2-3 hours (or sooner if you smell a poop—you’ll learn that scent fast!) .
- Check diapers every 1-2 hours for newborns (they can’t tell you when they’re wet, so we’ve got to be their voice!).
- After feedings: Always change their diaper—feeding time is messy, and a clean diaper means a happier baby (and fewer leaks!).
- Dirty diapers: Change immediately! Not just for hygiene, but to keep their soft skin rash-free . Plus, a clean diaper = a happy baby who’s ready for more snuggles.
How Many Diapers to Buy before a Baby Comes?
The last thing you want as a new mom is to run out of diapers at 2 AM (we’ve all been there, and it’s not fun!). Here’s our kind, practical advice—with a clear, actionable starting point:
👉 Start with 200 Newborn (NB) Diapers—Your Perfect Baseline!
This is the sweet spot for expectant moms: 200 newborn-sized diapers (this is roughly 9–10 packs of Aiwibi NB diapers) will comfortably cover the first 17-20 days of your baby’s life (based on 10-12 diapers/day). It’s enough to avoid panic runs to the store during those sleep-deprived early weeks, but not so many that you’ll be stuck with unused diapers if your baby grows quickly (most outgrow NB size in 4-6 weeks!).
👉 Also prepare 1 pack of Size P (Size 1) diapers—just in case!
While newborns usually start in NB diapers, many babies hit growth spurts faster than expected. Some babies outgrow NB size as early as Week 3! Preparing one pack of Size P diapers gives you a smooth transition, ensuring you’re not stuck with diapers that feel snug or cause leaks.
This tiny backup plan saves you late-night panic, avoids waistline marks, and lets you swap sizes the moment you notice a better fit. Think of it as “future-proofing” your diaper stash—practical, easy, and stress-free for new moms.
