How many baby diapers per day and month?

It's one of the questions that many expectant mothers and parents ask themselves during pregnancy, especially those experiencing their first pregnancy: how many diapers should a baby use every day?

It's a practical question, because planning the number of diapers your baby will need not only helps you keep a stock of diapers, but also helps you budget for diapers, which, as we all know, represents a considerable cost.


How many diapers should I plan for my stay in the maternity ward?

If you're packing your suitcasefor the maternity ward and wondering how many diapers you'll need for baby's first few days?

At birth, you'll need to change your baby's diapers every two to three hours, or at every feed or bottle-feeding, but you can change the diaper as often as necessary. A newborn baby generally has three bowel movements a day, and urinates every two to three hours.

Bear in mind thatprolonged contact with stool can irritate baby's skin, that bacteria in urine can cause urinary tract infections, particularly in little girls, and that keeping a diaper wet can lead to the development of diaper rash. What is diaper rash? It's a fairly common skin inflammation that causes red, sensitive, blistered skin.

What's more, if you don't change your baby's diaper often enough, it can lead to accidents involving your baby's clothes, bed or car seat.

For maternity use, it's estimated that you'll need around 8 diapers a day, so a pack of 30 will suffice. This will give you enough diapers to be prepared for any accidents in everyday life, while not bringing an inordinate stock for your stay in the maternity ward.

How many diapers per day for a newborn (0-3 months)?

The official recommendations of midwives and pediatricians are to change a newborn's diaper every time he or she feeds or drinks (earlier if there is stool).

A newborn baby feeds or drinks a bottle regularly, every three hours or so. This means changing every three hours (even at night!).

Babies don 't sleep through the night immediately. Not all babies are equal when it comes to the age at which they (finally) sleep through the night. But in general, it's estimated that after a month or so, babies are already starting to space out their wakings and feedings, and to sleep more at night.

For a baby who is not yet sleeping through the night, if he wakes up every 3 hours or so to feed, this means a change every three hours, i.e. 8 days a day, or 240 days a month.

How many diapers do I need for a young baby (9 to 36 months)?

The number of diapers you need will change as your baby grows. The bigger he gets, the more frequent his feedings become. Bowel movements become more predictable and urination less frequent. Your nights will also get longer.

Even so, there's no precise answer to the number of diapers your child will need. However, it is possible to get an idea of what is needed.

The bigger your child gets, the fewer diapers he needs

As your baby grows, the number of diapers he needs will decrease.

Generally speaking, at 9 months of age, your baby starts to eat the same menus as you, even if they're blended. Many children are already sleeping through the night. We estimate that the number of diapers is reduced to 5 or 6 every 24 hours, which works out at around 150 diapers every 30 days.

Then, the number of diapers needed per day is gradually reduced, depending on each child's rhythm of course, but estimates give the following figures:

  • From 13 to 20 months, children use around 4 to 5 disposable diapers a day;
  • From 20 to 30 months, from 3 to 4 diapers a day;
  • From 30 to 36 months, 2 to 3 diapers are generally sufficient.

In all cases, in the event of bowel movements, the child should be changed quickly to avoid maceration of the stool with the skin of the buttocks. This can lead to irritation, redness and even infection.

To avoid any kind of irritation, we recommend using organic diapers, which are much gentler on your child's bottom.

You can either change your baby's diaper as usual at feeding time, or make an extra change part of your routine.

Other factors can also influence the number of times you change your baby, such as the weather. Indeed, if it's warmer, your baby will drink a bottle of water and, potentially, the diapers will be filled more quickly. The diaper needs to be changed more regularly.

If you're breast-feeding your baby, you'll probably also need extra diapers.

So it's hard to predict a precise diaper-changing rhythm, because every baby is different, and several factors can also play a part in this figure.

Adapting diapers to your child's age and weight

As your little one grows, the size of diapers you'll need to provide. Depending on your child's weight, you'll need to choose a different diaper size.

Especially in the first few weeks of your baby's life, he tends to grow rapidly.

How many diapers does a baby need?

It's difficult to give a precise figure for the number of diapers a baby will use in his lifetime. But, if we consider an average with the examples we've seen above, we'd say that :

  • During the first two months of life, an infant uses around 240 per month.
  • From the 3rd month to the first year of life, it needs around 150 a month.
  • From the age of 1 to 2, this number is gradually reduced to 120 per month.
  • And finally, from 2 to 3 years of age, depending on the child's cleanliness, he'll need just one more, for night-time use.

This gives us a range of 3800 to 4800 diapers, depending on the age at which your baby becomes potty-trained.

Think ahead about the number of diapers per month!

To avoid running out of diapers for your baby, it's important to keep an eye on your stock. But you shouldn't plan for too much stock either, because as baby grows, the size you need to use is no longer the same. What's more, diapers represent a significant financial cost! Considering the average price of a diaper it makes more sense to buy them often than to stock up on diapers that your child will no longer be able to wear.

In fact, as explained above, a number of things can influence the frequency of diaper changes, such as the weather, whether or not your baby is breastfeeding, whether or not he sleeps through the night quickly, when he starts diversifying his diet... In short, many factors can influence the number of diapers to be used per day.

And, quite simply, the number of diapers varies from baby to baby, because everyone is different.

To be on the safe side when it comes to the number of diapers to use, you can adopt the subscription delivery system: you can choose how often you want to be delivered, as well as the size you need.

Of course, the aim is to have enough diapers, without having to carry a lifetime's supply!

How many diapers per month for twins?

If you've just had twins, or if you're expecting twins, you'll need to double the number of diapers. Twins evolve at different rates. The same goes for diaper sizes: when one child moves up to the next size, the other may still be in the next size down.

Dear parents, to make sizing easier for you, you can adopt our subscription system with pack delivery.

After 3 years: the start of potty training!

Finally, when your baby reaches the age of 3, he'll be potty-trained, meaning he'll be able to fill his potty on his own and gradually use far fewer diapers. Some children will be potty-trained by the age of 2, while others will take much longer. Again, this is an average and every child is different.

When your child is old enough to tell you when he or she wants to go potty, you can switch to the training pants or washable, reusable diapers. It's a more ecological alternative to the classic diaper.
