Newborns (0-3 months)

For the first few months, you can expect your baby to use about 10 diapers a day. That’s about 70 diapers a week. Newborns usually need to be changed every 2 to 3 hours.

How many diapers per day?

Most newborns will wet 8 to 12 diapers in a day. That’s about one diaper every two to three hours. However, some babies may need a diaper change as often as every hour, especially in the early weeks.

You can expect your baby to use:
-3 to 5 diapers per day for the first few weeks
-2 to 4 diapers per day by the end of the first month
-1 to 2 diapers per day by the end of the second month

As your baby grows and has fewer wet and soiled diapers, you’ll probably change them:
-4 times per day during weekdays
-5 times per day during weekends or when you’re home
-6 or 7 times per day when you’re traveling or away from home

How many diapers will you need total?

On average, a newborn baby will use 10 diapers per day. This means that you will need to purchase between 70 and 80 diapers each week. Over the course of a month, you can expect to use between 280 and 320 diapers. In terms of total cost, this means that you will spend between $70 and $80 per month on diapers.

Infants (3-9 months)

You can expect your baby to use about 5-6 diapers per day during their first few months. This means you will need to purchase about 30-36 diapers per week. Newborns will usually need size 1 diapers, but some may need size 2 diapers. Once your baby starts to move around more and becomes more active, they will probably need size 3 diapers.

How many diapers per day?

On average, your baby will use between 5 and 9 diapers per day during their first 3 months of life. This increases to between 8 and 12 diapers per day during their second 3 months, and then declines to between 6 and 10 diapers per day during their third 3 months.

To give you a more specific idea, infants in their first week use about 10-12 diapers per day. This then declines to an average of 8-10 diapers for the remainder of the first 3 months. For the second 3 months, your baby will likely use about 6-9 diapers each day.

During the third and fourth trimesters, you can expect your baby to use 4-6 diapers each day.

How many diapers will you need total?

You can plan on changing diapers anywhere from 5-12 times per day, or about 35-42 times per week. A good average is about 8-10 diapers per day, or 56-70 diapers per week.

This means you will go through anywhere from 2,520 to 4,840 diapers in the first year! Phew!

Toddlers (9-18 months)

Depending on how often you do laundry, you’ll need between 5 and 9 diaper changes per day. That’s anywhere from 35 to 63 diapers per week. You can use this number as a guide, but every baby is different so you may need to adjust based on how often your little one goes.

How many diapers per day?

On average, a baby uses about 10 diapers per day during their first few months of life. This means you will likely go through between 70 and 80 diapers each week! After your baby gets a little older and starts solid foods, they will probably use fewer diapers during the daytime hours. However, they may start pooping more at night and may need an extra diaper or two then.

How many diapers will you need total?

If you’re using disposable diapers, you can expect your baby to use an average of 6 to 10 diapers per day. This means you may need to buy anywhere from 2,880 to 4,800+ diapers in their first year! If you use cloth diapers, the number of required changes will be lower (4-8 per day), but you’ll still need a good stock — we recommend starting with 24 cloth diapers.
