New parents often wonder how many diapers their baby will go through in the first year. The number of diapers a baby uses can vary quite a bit depending on factors like the baby’s size, feeding method, and individual habits. However, there are some general guidelines that can help estimate diaper usage in baby’s first year.
How many diapers do newborns use?
In the first few days after birth, babies will go through 6-10 diapers per day. This number increases rapidly as babies eat more and their intestinal tracts mature. Here’s a rough estimate of how many diapers you can expect a newborn to use per day:
- First week: 8-12 diapers per day
- 1-2 weeks old: 10-15 diapers per day
- 3-4 weeks old: 15-20 diapers per day
So in the first month alone, you can expect your newborn to go through at least 300-600 diapers. Stock up!
How many diapers do babies use at 1 month old?
By one month of age, babies usually go through about 15-20 diapers per day. Going with an average of 18 diapers per day, you would need approximately 540 diapers for the entire month.
How many diapers do babies use at 2 months old?
At 2 months old, babies go through around 15-25 diapers per day, with an average of 20 diapers. For a full month that would equal about 600 diapers.
How many diapers do babies use at 3 months old?

How many diapers do babies use at 7 months old?
As babies get more efficient at solid feeding and their digestive systems mature, they tend to need fewer diapers again. Expect around 12-15 diapers per day for a 7 month old. For the month, you’ll need 360-450 diapers.

To be prepared with enough diapers, it’s recommended to have at least a 2 week supply on hand at all times. Stocking up on 200-300 diapers per month is a safe bet.
Factors affecting diaper usage
While these numbers provide a general guideline, every baby will go through diapers at a slightly different pace. Here are some factors that can affect how many diapers your baby uses:
- Baby’s size: Larger babies require bigger diapers that hold more urine, meaning more frequent changes.
- Feeding method: Formula fed babies tend to have more frequent stools than breastfed babies.
- Solid foods: Introducing solids can make stools more solid, allowing longer times between changes.
- Health: GI issues like reflux, constipation or diarrhea can increase dirty diapers.
- Sleep patterns: Babies who take long naps go longer between changes.
- Activity level: Active babies who wiggle a lot may need more frequent diapering.
- Potty training: As babies learn to use the toilet, diaper needs decrease.
Signs your baby needs more diapers
No one wants to run out of diapers when you have a little one at home! Here are some signs you may need to buy more diapers:
- Your diaper supply is running low with more than a week to go until you planned to buy more.
- You’re finding yourself scraping the bottom of your last diaper pack.
- You don’t have at least a 2 week supply stocked up.
- Your baby is going through diapers faster than normal due to a growth spurt, illness or other factors.
- You notice your baby has red marks from sitting in a wet diaper too long.
erring on the side of extra diapers is smart – babies seem to have a way of going through them right when you least expect it! Being prepared with enough diapers helps avoid late night emergency store runs.
