How Many Bottle Do I Need For Baby

Whether you plan to breastfeed your child or use infant formula, the number of baby bottles you will need can range anywhere from four to twelve. This number is determined by the general rule. It is highly recommended that you have at least 8–10 bottles on hand before the birth of your baby.

The arrival of a new child into your family can be both an exciting and overwhelming time, especially if this is your first child. When you first have a baby, you probably have a lot of questions and you probably search Google a lot for answers to those questions. It’s nothing to be concerned about; that’s perfectly normal.

One of the most important responsibilities you have is to watch over your child’s eating habits. So, at this point, you might be wondering how many bottles you need to purchase and stockpile. The precise number is determined by a number of factors, including the age of your child as well as whether or not you are breastfeeding. When looking for bottles, here are some things to keep in mind, as well as the different kinds of bottles that are available.

How many bottles do I need for a single day?

Every baby is different. How many bottles you need each day will depend on factors like your baby’s age and whether you are breast-feeding, using formula or a combination of the two. There is no specific recommended number of bottles you need to buy to achieve peak feeding. But you should consider how often your baby eats and especially how often you want to clean the bottles. 

You can expect to feed your newborn baby every two to three hours. They may need to eat more frequently if you are breastfeeding because breast milk is digested faster than formula

We’ve rounded up the standard recommendations for how many baby bottles you need based on your baby’s age and feeding habits.

One to four baby bottles

If you are home and breastfeeding your baby, you won’t need as many bottles. You’ll likely only need to have one to four bottles ready to use per day. Of course, you’ll want to have a few bottles on hand if you need to step out to run an errand. You can also consider having a few bottles around if you prefer to bottle feed your baby in public or if your partner wants to take part in feedings. 

Bottles become less important as your baby gets older. You’ll need fewer bottles if your baby is past the six-month mark and beginning to supplement with solid foods. In this case, experts recommend feeding them formula or breastmilk from a cup instead of a bottle.

Three to six baby bottles

It’s common for babies to feed five to six times per day in the two-month to five-month age range. If you are doing a combination of breastfeeding and bottle feeding, your will likely need fewer than six bottles a day. Consider how often you need to clean the bottles. If you don’t want to worry about cleaning the bottles every time your baby needs to eat, you can buy a few more. 

Six or more baby bottles

Within the first month, newborns need six to eight feedings per day of around two to four ounces of milk. As your baby grows into their second month, how often you are feeding them may decrease because they are eating more at one time. 

If you are also breastfeeding your baby, they will likely need fewer than six to eight bottles per day during that first month. However, if you’re a working mom or will be away from your baby for periods of time, it’s best to have more bottles on hand. You want to have enough to cover the entire time you’re away.

How to find your ideal baby bottle

Now you have an idea of how many bottles you need, so let’s talk about which bottles are best for your situation. There are a few factors to consider when choosing bottles for your little one. It comes down to the types of baby bottles and the materials used to manufacture them.

Types of bottles

There are several bottle types to consider. Each comes with pros, cons and specializations. Some parents choose to keep a variety on hand to fit different needs.

Standard bottles

Standard baby bottles are basically what comes to mind when you picture a baby bottle. They are the most common bottles you see at stores and are typically what parents use for everyday needs. With a standard baby bottle, you don’t get any bells and whistles. They are dependable and offer the most standard fits for teats and accessories. Standard baby bottles are generally the most affordable option.

Anti-colic bottles 

Sometimes, babies swallow air when using standard bottles, leading to painful gas and indigestion. This can cause your baby to have prolonged fits of crying, also known as colic. Colic is most common during the first six weeks and will usually go away on its own. Anti-colic bottles are designed to help prevent your baby from swallowing air while they eat. This type of bottle is typically more expensive than standard bottles and is more difficult to clean. However, if you’ve noticed your baby tends to swallow air, it’s worth it. 

Self-sterilizing bottles

Self-sterilizing bottles are designed to be quickly and easily sterilized in the microwave. You’ll fill a small portion of the bottle’s base with water and place the bottle’s parts on top. Then, you place it in the microwave for a few minutes to steam sterilize. 

Disposable bottles

These single-use bottles come ready to use and are relatively inexpensive. But using them frequently can quickly become more expensive than feeding your baby with reusable bottles. They also aren’t eco-friendly.

Baby bottle materials

There are a few different materials commonly used in the production of baby bottles. Plastic, glass, silicone, and stainless steel are most common within the US. Each material comes with its benefits, downsides and price points. While some materials may be better for some circumstances, the final selection may be a matter of preference.

Plastic bottles

Plastic bottles have traditionally been the most common, though there are some issues to consider. In the past, plastic baby bottles had the industrial chemical Bisphenol A (BPA) in them. In 2012, the US Food and Drug Administration banned the plasticizer BPA from baby bottles due to health concerns. However, some chemicals that are still allowed in plastic bottles may make you uncomfortable about using them. Despite potential health concerns, plastic does offer an inexpensive and durable option. If you decide to go with plastic bottles, avoid ones with BPA, BPS, Phthalates and PVC.

Glass bottles

Glass bottles don’t have the risk of chemicals that plastic bottles do. They are also easy to sanitize and can withstand high temperatures. The downside of glass bottles is that they are more expensive and can break. They may also be too heavy for your baby, who may try to grab the bottle while eating. 

Silicone bottles

Food-grade silicone bottles are a favorite among parents since they are shatter-proof like plastic but don’t run the same risk of harmful chemicals. If you’ve decided that you want silicone bottles for your baby,  ensure the product is made with food- or medical-grade silicone. Note that silicone bottles are generally more expensive than plastic and glass bottles.

Stainless steel bottles

Stainless steel bottles are often more expensive, but they come with upsides others don’t have. For instance, stainless steel bottles withstand high temperatures, are lightweight and easy to hold and won’t shatter. The main downside of stainless steel bottles is the cost and there is the risk of them containing lead. To ensure that your baby bottle is lead-free, purchase #304 or 18/8 food-grade stainless steel.

Other considerations

There are other decisions that go into buying baby bottles. There are various accessories and components: nipples, venting systems, breast pump attachments and so on. You need to make sure they all can work together. Unfortunately, products aren’t universally compatible, so do your research before you shop. 

Different bottles also have various widths of the neck, which can impact how easy it is to clean and will determine which nipples will fit. Beyond that, it’s best to ensure you choose bottle types and materials that are you are comfortable with.

How Many Baby Bottles Do I Need If Breastfeeding

Feedings occur on average between 10 and 14 times in the first 24 hours of a newborn baby’s life, with the frequency of feedings gradually decreasing as the baby gets older. To get started, you will probably need anywhere from four to six bottles and teats if you plan on exclusively bottle feeding your child, whether with formula or with breast milk that has been expressed.

Having a baby is an exciting time, especially for first-time parents.

However, when it comes to feeding time, knowing the best choice can be confusing with the many different options available.

Breast-feeding is one of the healthiest options, but there may be times when you will need to use a bottle for your baby even if you are breast feeding.


The general rule for the number of baby bottles you will need ranges from 4 to 12, depending on whether you will use formula, or you will breast feed. It will be best to have at least 8-10 bottles on hand before your baby is born. 

You will want to start with five-ounce bottles and then move to eight-ounce bottles until the baby is about four months old.

Once the baby reaches four months, you will need to buy larger bottles to accommodate the child’s growing appetite.

Formula or Breast Feeding If you plan to use formula for your baby, you will need to consider how often you plan to wash and sterilize the bottles.

You will also want to determine if you will prepare bottles in advance or make them as you need them.

Even if you plan to breastfeed, you will need bottles on hand, especially if you plan to return to work while you are still breastfeeding.

The First Months

In the first few months, you should plan to feed your baby every two to three hours if you are breastfeeding, including the overnight hours.

If you are breastfeeding, you may find that the child eats more often than a child who is formula-fed.

As your baby grows, the nutrients in your breast milk changes to ensure that the child is getting what they need to grow.

If you are not able to breastfeed, use a breast pump to maintain your breast supply. Store it at the appropriate temperature in bottles.

You won’t want to force your child to empty a bottle of breast milk as it may have more than what the child normally eats.

Bottles Needed for First Few Months

During the first month, your child will more than likely eat six to eight times per day, around two to four ounces at a feeding.

This will mean you need four to six four-ounce bottles per day for formula fed babies while you may be fine with just one or two for breastfed infants.

During the second month, the child will eat five to six times per day and consume around five to six ounces.

This means you may need larger bottles.

From three to five months, the child’s feedings will be around the same number per day, but they will consume six to seven ounces.


You need to have four to six 8-ounce bottles per day for formula fed babies.

Because many mothers return to work after the second month, if you are breast feeding you will need five or six bottles for breast fed babies as well.

After Six Months of Age

Once a child reaches six months of age, you should still only offer breast milk or formula in bottles until they are at least one year old.

You should not offer juice in cups or bottles until your child is at least one year old.

At six months, your doctor may advise you to start giving your child solid food which will reduce the amount of formula or breast milk they will need.

However, you will still need to keep bottles on hand until your child is around one when they can be easily transitioned to a cup with a lid.

You will want to have four or five larger bottles on hand between the ages of six and 12 months.

Keep in mind that children will be more curious at this age, so you want to choose nipples and tops that the child cannot open on their own.

Types of Bottles

There are many different types of bottles available and you want to choose the one that works best for you and your child.

The bottle should be convenient to use and allow for easy feeding of your baby. If you plan to breastfeed, you want a bottle that allows you to express, store and feed your baby, avoiding the need to transfer milk from one container to another.

Choose bottles that will also grow with your child and has a secure lid system that is not easy for your child to open.

As your child grows, they will begin to hold the bottle on their own, so you also want to find one that is easy to grip. Storage is also important.

You want bottles that are easily stacked and can be carried in a diaper bag without taking up too much room.

Of course, a bottle that is easy to clean is also very important.

Your Ideal Baby Bottle: Things to Look For 

Some of the features to look for in baby bottles include:

Natural shaped nipples that allow for easy latch on and reduces nipple confusion in breastfed babies

  • Tilted nipples that reduce back-flow which can lead to ear infections
  • Air venting to reduce aeration in order to prevent upset stomachs
  • One-handed closure so you can securely close the bottle while holding the baby
  • Easy cleaning
  • Easy to grip

Choosing the right baby bottle is an important part of preparing for a new addition to the family.

The number of bottles you will need depends on your child, your ability to clean those you have used and other factors.
