During preparations for the arrival of a baby, diapers always appear at the top of the shopping list. They are an essential product from day one, but at the same time they generate many uncertainties: how many diapers to buy before birth, is it worth stocking up, what sizes to choose, and what to do if the baby grows faster than expected.
These doubts are normal, especially for first-time parents. The reality is that there isn't a single number that's valid for all families. What exists is a correct way to plan, reducing risks, avoiding waste, and ensuring peace of mind in the first few weeks.
Why it's important to plan for diapers before birth
In the first few days after giving birth, parents are focused on recovery, the baby, and adjusting to the new routine. Having to go out to buy diapers or make urgent requests is not the ideal scenario.
Planning for diapers before birth allows you to:
- Avoid emergency purchases.
- Reduce stress in the first few days.
- Make sure the baby has appropriate diapers from the very first moment.
- Make the most of promotions and packages without compromising your choice.
At the same time, over-planning can result in diapers that quickly become too small, especially in the initial sizes. The goal is balance.
How many diapers does a newborn use in the first few days?
A newborn baby uses, on average, between 8 and 12 diapers per day. This number can vary, but in the first few days it's normal for the baby to need many changes due to the frequency of feedings and bowel movements.
In practice, this means that, in a week, consumption can easily reach 60 to 80 diapers. In the first month, average consumption is between 240 and 360 diapers, depending on the baby, their routine, and how diaper changes are done (for example, preventative changes before sleep).

What diaper sizes should I buy before giving birth?
One of the most important decisions is choosing the right sizes for your initial stock. The safest recommendation is to combine an initial size (RN/T1) with a small margin for the next size (T2), avoiding buying excessive quantities of a single size.
Newborn diapers (NB or T1)
Newborn (RN) or size 1 diapers are generally recommended for babies weighing between 2.5 kg and 5 kg. They are designed for the first few days and weeks, with softer materials and a delicate fit. However, some babies use this size for a very short time, while others remain in it for several weeks.
Therefore, the safe recommendation is to buy a moderate amount of this size, enough for the first few days, but not in excess.

Size 2 (T2)
Size 2 is typically used when the baby weighs more than 4 kg. Many babies quickly transition from newborn/T1 size to size 2, especially if they are born with a higher weight. Therefore, it makes sense to include some size 2 stock in your initial preparation now, even before birth.

How many diapers to buy before giving birth: a practical recommendation.
For most families, a balanced foundation before birth might be:
- 1 to 2 packs of newborn or size 1 diapers.
- 1 pack of size 2 diapers.
This initial stock is usually enough to cover the first 1 to 2 weeks, assess the diaper fit for the baby, and understand the growth rate. After this period, parents can better adjust subsequent purchases based on the baby's needs.
Because it's not advisable to stock up on large amounts of food before the birth.
Despite the temptation to take advantage of promotions, stockpiling a large amount of food before the birth has real risks:
- The baby may be born larger than expected and quickly "skip" the newborn/trimester stage (RN/T1).
- The baby may have sensitive skin and may not adapt well to a particular diaper.
- Growth can be faster than average, reducing the useful lifespan of each size.
Furthermore, when you buy too much, you lose the flexibility to adjust your choice (line, brand, type) to what works best for that baby.
Diapers and sensitive skin: a decisive factor.
Many newborns have sensitive skin, even without prior signs. An ill-fitting diaper can cause diaper rash in the first few days. If there is a family history of sensitive skin or if you want to prevent problems from the start, it may make sense to begin with diapers designed for greater softness and dermatological care.

Wet wipes and other essential items to consider.
When planning diapers, it's also important to think about complementary products. Wipes are part of the daily routine from day one. Choosing wipes specifically formulated for newborns helps reduce irritation and contributes to healthy skin.

Diapers in the first 30 days: what changes
The first month is a period of great adjustment. Diaper use is high and the baby's body changes rapidly. Therefore, initial planning should be flexible.

Initial costs and financial planning
Even before the baby is born, it's helpful to have an idea of the medium-term financial impact of diapers. This helps in planning purchases, choosing packages when it makes sense, and avoiding hasty decisions.

Cheap diapers from the start: is it a good idea?
Some parents look for cheaper diapers right from the birth. While it's legitimate to consider the budget, in the first few days the priority should be comfort and skin protection. There are ways to save money without compromising quality, but this requires clear criteria.

List of common mistakes when buying diapers before birth.
Some mistakes are repeated frequently:
- Buying lots of newborn/size 1 diapers "just to be safe," and then having leftover stock.
- Choosing solely based on price, without evaluating absorption and impact on the skin.
- Do not consider the possibility of sensitive skin.
- Ignoring the baby's rapid growth in the first few weeks.

Practical alternative: gift certificate
For those who want to help expectant parents or prepare without taking risks, a gift certificate is a practical solution. It allows you to choose the right diapers after the birth, when the needs are clear and the size is confirmed.

Knowing how many diapers to buy before the baby is born is a matter of balance. A well-planned initial stock reduces stress, avoids waste, and ensures comfort from day one.
The safest strategy involves buying moderate amounts, including a little of the next size up, observing how the baby adapts, and adjusting purchases over the first few weeks. With information and planning, it's possible to begin this new phase with more peace of mind and confidence.
