When it comes to preparing for your baby’s arrival, choosing the perfect stroller, softest swaddle, or cutest crib sheets can be exciting — but one of the most important essentials you’ll rely on every single day is diapers.
If you’re building your baby registry, it’s smart to think ahead about how many diapers your little one will need and in what sizes. Babies grow fast, and their diaper needs change just as quickly! Here’s a complete guide to help you plan — from the newborn stage to your baby’s first birthday.
👶 How Many Newborn Diapers Do You Need?
In the first few weeks of life, newborns go through 10–12 diaper changes per day — that’s about 325 diapers in the first month alone!
Why so many? Newborns typically need a diaper change after every feeding, which happens about every two to three hours. But don’t worry — this stage doesn’t last forever.
As your baby grows, their bladder also grows, meaning fewer changes each day:
-
2–3 months: 8–10 diapers per day
-
3–6 months: 6–8 diapers per day
-
6–12 months: about 5 diapers per day
That means by the end of your baby’s first year, you’ll likely go through 2,500 to 3,000 diapers total.
🍼 How Many Diapers to Add to Your Registry
Your baby registry is a great way to start building your diaper stash — or to ask for diaper funds and gift cards that help you stock up as your baby grows.
Here’s a general guide for what to include:
Newborn Size (Up to 10 lbs)
-
Only 1–2 packs (120–240 diapers total)
-
Many babies outgrow this size quickly or skip it altogether.
Size 1 (8–14 lbs)
-
Around 4–6 boxes
-
Babies typically wear this size for 2–3 months.
Size 2 (12–18 lbs)
-
Around 5–6 boxes
-
Usually lasts through the 4–7 month range.
Size 3 (16–28 lbs)
-
Around 6 boxes
-
Most babies will stay in this size until their first birthday.
💡 Tip: If you have limited space, focus on sizes 1 and 2, since those will get the most use early on.
🚫 Don’t Stock Up Too Much on Newborn Diapers
Most hospitals will send you home with plenty of newborn-size diapers. And since babies grow fast (they can gain up to 3 pounds in the first month), you might not need to buy many of your own.
Unless your baby is born smaller than 7 pounds, you’ll likely switch to size 1 within a few weeks.
🧺 Register for Multiple Brands
Every baby is different! Some diapers fit snugly and prevent leaks, while others may irritate sensitive skin. Because of this, it’s a good idea to try out different brands before committing to one.
At MacroBaby, you’ll find a variety of trusted diaper brands — including Honest, and Eco by Naty — so you can test what works best for your baby.
If you receive diapers that don’t fit well or cause irritation, most retailers (like Target or Walmart) allow exchanges for unopened boxes. You can also donate extras to local shelters.
💰 Save Money on Diapers
Buying in bulk can make a big difference in price per diaper. For example:
-
A bag of Pampers Swaddlers (32 count) = about $0.40 per diaper
-
A box of Pampers Swaddlers (164 count) = about $0.27 per diaper
Subscribing to an auto-delivery program or registering for a diaper subscription can also save you time and money. You’ll never run out — and you’ll often receive discounts for recurring orders.
If you’re short on space, ask for MacroBaby gift cards or create a diaper fund on your registry so you can buy diapers as needed.
🌿 How Many Cloth Diapers Do You Need?
If you prefer cloth diapering, you’ll still want to keep some disposable diapers on hand, especially for the early days.
Here’s what most cloth diapering parents recommend:
-
20–24 cloth diapers total if washing every 1–2 days
-
14 cloth diapers if you plan to wash daily
Some parents start with disposables for the first month (when babies need very frequent changes) and transition to cloth later.
🧾 The Bottom Line
Between changes, sizes, and brands, it might sound like a lot — but with a little planning, you’ll always have what you need.
Your baby will use around 2,500 to 3,000 diapers in their first year, so stocking up early (and smartly) will save time, money, and stress.
At MacroBaby, you can find everything you need to make diaper duty easier — from diapers and wipes to changing pads, diaper bags, and creams — all in one place.
