This is a question that many new parents ask themselves. The answer really depends on how often you do laundry and how often your baby is wearing them. A good rule of thumb is to have at least 3-4 days worth of baby onesies on hand.

This way, you can do a load of laundry every other day and not have to worry about running out of clean clothes for your little one.

If you’re anything like me, you probably overthink everything when it comes to your baby. What kind of car seat do I need? How many diapers should I buy? And most importantly, how many baby onesies do I need?

The answer to this question is actually pretty simple. You’ll need about 10-12 baby onesies for your little one’s first few months. This may seem like a lot, but trust me, you’ll be glad you have them. Baby clothes get dirty quickly, and it’s always good to have a spare on hand. Of course, every family is different and you may find that you need more or less than 10-12 baby onesies.

But this is a good starting point if you’re unsure of how many to purchase. You may choose a camo baby onesie from the online store.

How Many Onesies of Each Size Do I Need?

As a first-time parent, you may be wondering how many onesies you need in each size. The truth is, it varies based on a few factors. Here are a few things to consider when deciding how many onesies to buy in each size:

How Many Baby Onesies Do I Need?
  1. How often will you do laundry? If you do laundry every day or two, you won’t need as many onesies as someone who only does laundry once a week.
  2. How much will your baby spit up? Some babies are little pukers and go through several outfits a day. Others don’t spit up much at all. Obviously, the more Spit-Up-friendly your baby is, the fewer onesies you’ll need overall.
  3. What’s the climate like where you live? If it’s hot where you live, your baby will probably only need one or two outfits per day (including a Onesie). But if it’s cold where you live, your baby may need three or four outfits per day (again, including a Onesie).

Assuming that you’ll be doing laundry every other day and that your baby doesn’t spit up excessively, here’s a rough guide for how many Onesies you’ll need in each size: – Newborn: 6-8 Onesies – 3 months: 6-8 Onesies – 6 months: 4-6 Onesies – 9 months: 2-4 Onesies

How Many Onesies are Needed for Baby?

A newborn baby will typically go through 10-12 onesies per day. In the first week, they may even go through 14-16! So, if you’re doing laundry every other day, you’ll need at least 20-24 onesies on hand.

If you have a baby shower before your little one arrives, ask for onesies as gifts so you can stock up.

How Many Onesies Does a Newborn Go Through a Day?

On average, newborns go through 8-10 onesies a day. This number can vary depending on how often they are eating and whether they are spitting up or not. If you have a particularly messy eater, you may want to have more than 10 on hand!

Is 0 to 3 Months the Same As a Newborn?

No, 0 to 3 months is not the same as a newborn. Newborns are generally born within the first month after conception and spend their first few weeks of life adapting to their new environment outside the womb. The 0 to 3 month period is considered the infancy stage, during which babies grow and develop rapidly.

How Many Onesies Do I Need for 0-3 Months

If you’re on the hunt for how many onesies you need for your 0-3 month old, don’t worry, we’ve got you covered. The average baby will go through about seven to eight onesies a day during this stage, so it’s important to have a good stock pile. However, every baby is different and some may go through more or less depending on their size and how often they spit up or have diaper blowouts.

To be safe, we recommend having at least three dozen onesies on hand for those first few months. This way, even if your baby has a particularly messy day (or week), you won’t have to do laundry every single day. Plus, it’s always nice to have a few backups in case of accidents. When it comes to picking out the perfect onesie, there are a few things to keep in mind.

First, make sure the fabric is soft and breathable so your little one stays comfortable all day long. Second, choose a style that has easy access for diaper changes – nobody wants to be fumbling with buttons in the middle of a dirty diaper change! Third, pick something that’s machine washable and dryer friendly for easy care. And finally, don’t forget about style! Even though they’ll only be wearing it for a few months, you want your baby to look cute and stylish in their onesies.

So there you have it – everything you need to know about how many onesies you should have on hand for your 0-3 month old. Now get shopping!


A recent study shows that the average baby will go through 8-10 onesies per week in their first year. That’s a lot of laundry! So how many should you have on hand?

The rule of thumb is to have 3-4 times as many newborn onesies as you think you’ll need. They grow so fast, and you never know when a blowout will happen. Once they start crawling and eating solid food, the number of blowouts decreases, but they’ll still need several changes per day.

If you plan to use cloth diapers, you’ll need even more onesies since they require more frequent changing. A good rule of thumb is to have at least 20-30 onesies on hand for a newborn using cloth diapers. No matter how many you end up needing, make sure to stock up on cute designs!

Babies outgrow clothes quickly, but it’s always fun to look back at photos of them in their tiny outfits.
