How many newborn diapers do I need to buy?

Quick Answer

You will likely need between 70-90 diapers per week for a newborn baby. This equates to 280-360 diapers for the first month. However, every baby is different so you may need more or less. Stock up on various sizes to accommodate growth spurts.

How Many Diapers Does a Newborn Use Per Day?

Newborns urinate and have bowel movements very frequently, going through 8-12 diapers per day on average. However, this can vary significantly between babies. Some newborns may only go through 6 per day, while others may require up to 15 or more.

Factors that affect diaper usage in newborns:

  • Baby’s size – Larger babies will require bigger diapers that hold more.
  • Feeding method – Breastfed babies tend to have more frequent bowel movements.
  • Health issues – Diarrhea, constipation, etc. can increase or decrease usage.
  • Baby’s bladder size – Some babies have smaller bladders and urinate more often.

As a new parent, you’ll quickly learn your own baby’s habits and optimal diapering schedule. Expect frequent diaper changes around the clock in the first couple months.

How Many Diapers Will I Need Per Week?

If your newborn uses 8-12 diapers per day, that equals 56-84 diapers per week. Most experts recommend having 70-90 newborn diapers per week as a safe estimate.

Here is an example breakdown of newborn diaper usage per week:

Low end: 8 diapers/day x 7 days = 56 diapers/week
Average: 10 diapers/day x 7 days = 70 diapers/week
High end: 12 diapers/day x 7 days = 84 diapers/week

This range allows leeway for days when your baby may go through more diapers than normal. It’s better to have extras than to run out!

How Many Diapers Will I Need for the First Month?

For the first month, you can estimate needing 280-360 newborn size diapers based on using 70-90 per week.

Here’s a breakdown of the newborn diaper quantity needed for the first 4 weeks:

Week 1 70-90 diapers
Week 2 70-90 diapers
Week 3 70-90 diapers
Week 4 70-90 diapers
Total for Month 1 280-360 diapers

Buying in bulk packages can help minimize costs. Stock up on at least 300 newborn diapers to be prepared for the first month.

How Many Diapers Will I Need After the First Month?

Diaper needs tend to increase significantly after the newborn phase as babies grow bigger and start eating solid foods. Here are some estimates:

Months 2-3 90-120 diapers/week
360-480 diapers/month
Months 4-7 120-150 diapers/week
480-600 diapers/month
Months 8-12 140-180 diapers/week
560-720 diapers/month

As babies begin eating solids around 6 months, diaper usage jumps due to messier bowel movements. Toilet training may begin around 18-24 months, gradually decreasing diaper needs.

Stock up on larger sizes like 1, 2, and 3 as your baby grows. Consider buying different size bundles or variety packs.

Signs It’s Time to Size Up Diapers

As your newborn grows in the early months, you’ll need to size up their diapers to ensure a good fit. Here are some signs it’s time to move to the next diaper size:

  • Diapers leak frequently or don’t contain messes.
  • You’re changing diapers way more than normal.
  • Diapers seem tight on baby and leave marks.
  • There’s less than 1 inch of room left around waist and legs.
  • Diapers slide around and seem loose.
  • Baby is nearing top weight range for current size.
  • Rise feels too short and doesn’t reach belly button.
  • You’ve adjusted tabs to biggest setting.

Go up a size whenever diapers start feeling snug and leak-prone. Don’t wait until they’re bursting at the seams. Most babies grow out of newborn sizes around 10-14 lbs.

Newborn Diapering Supplies

Aside from the diapers themselves, there are some other supplies that can make diapering a newborn easier:

  • Wipes – Stock up on soft, gentle baby wipes for cleaning at each change.
  • Diaper cream – Apply with each change to protect delicate skin.
  • Changing pad – Provides a clean surface to change baby anywhere.
  • Diaper pail – Contains odors and keeps used diapers contained.
  • Diaper bags – For disposing or storing soiled diapers to wash.
  • Diaper rash ointment – Soothes and heals red, irritated skin.
  • Changing table – A designated place for safe, easy diaper changes.

Having these supplies on hand makes diapering a breeze!

Diapers are a big, recurring baby expense. Here are some tips for budgeting and saving on the diapering costs:

  • Estimate your monthly usage based on diapers per day.
  • Take advantage of sales, coupons, and rewards programs.
  • Buy in bulk online for bulk discount pricing.
  • Use cloth diapers to lower costs long-term.
  • Join Amazon Family or subscribe-and-save for regular deliveries.

With some savvy planning, you can stock up on diapers without breaking the bank. Prioritize your baby’s comfort and health above all else.
