If you are planning to breastfeed and are currently in the ‘nesting’ stage gathering all the essentials you may have asked yourself “How many baby bottles do I need if breastfeeding?” It’s a common question, and the answer depends on a few factors. In this post, I’ll guide you through the process of deciding how many bottles you might need and what factors to consider.

If you plan to breastfeed exclusively and are at home with your newborn baby most of the time, you won’t need as many bottles as bottle-fed babies – maybe just a few on hand for when you need to leave your baby with a caregiver or partner. Two to four bottles may be sufficient. However, if you plan to pump milk and store it for later use, you may need more bottles to accommodate your baby’s feeding schedule.

It’s important to note that every baby is different and newborn babies may have different feeding needs. As your baby grows and develops, their feeding habits may change, so it’s a good idea to have a few extra bottles on hand just in case.

By understanding your baby’s feeding needs and planning accordingly, you can ensure that you have the right amount of bottles to keep your little one fed and happy.

How Many Baby Bottles Do I Need If Breastfeeding?

So, how many baby bottles do you need? It primarily depends on whether your baby drinks expressed breast milk, formula, or a combination of both. First, consider how often your baby drinks from a bottle.

On average, breastfed babies only need baby bottles occasionally, so you may only need 2-4 bottles. You may need more if you plan to use a breast pump frequently and are often away from your baby.

If you’re exclusively bottle feeding with expressed milk or baby formula, you’ll need more bottles than a mother who’s primarily breastfeeding and only occasionally bottle feeding so you may need 8-10 bottles per day.

It’s always a good idea to have a few extra bottles on hand in case of emergencies or if you’re unable to wash them right away.

Breastfeeding vs. Bottle-feeding

When it comes to feeding your newborn, there are two options: breastfeeding and bottle-feeding. Both methods have their advantages and disadvantages, and it ultimately comes down to personal preference and what works best for you and your baby.

Breastfeeding Benefits

Breastfeeding is a beautifully natural way to feed babies. It provides numerous benefits to both the mother and the baby:

  • Breast milk contains all the necessary nutrients and antibodies that your baby needs to grow and develop.

  • It is easily digested and absorbed by the baby’s body.

  • Breastfeeding promotes bonding between the mother and the baby.

  • It can help reduce the risk of certain health conditions for both the mother and the baby, such as breast cancer and ear infections.

Bottle-feeding Benefits

Bottle-feeding also has its advantages:

  • It allows the father or other family members to participate in feeding the baby.

  • More flexibility and freedom for mom as she can pump breast milk and store it for later use.

  • Easier to monitor exactly how much milk the baby is consuming.

  • A good option for mothers who are unable to breastfeed due to medical reasons or personal preferences.

Types of Bottles

When deciding to buy bottles, consider the types of bottles available. Standard bottles, often made of plastic or glass, are the most common. Glass bottles are sturdy and easy to clean but can be heavy and more likely to break. On the other hand, a silicone bottle is a softer, more flexible option that many babies prefer. Let’s explore this further.

Glass Baby Bottles

Glass bottles are a popular choice because they are durable, easy to clean, and don’t contain any harmful chemicals. They are also a good option for parents who are concerned about the environmental impact of disposable bottles, as they are recyclable and can be reused many times.

However, glass bottles can be heavy and breakable, which may not be ideal for on-the-go feedings or for parents with young children who may accidentally drop them.

Plastic Baby Bottles

Plastic baby bottles are lightweight and shatterproof, making them a good choice for parents who are always on the go. They are also often less expensive than glass bottles, which can be a plus for budget-conscious parents.

However, some plastic bottles may contain harmful chemicals like BPA, so it’s important to choose a bottle that is labeled as BPA-free. Additionally, plastic bottles may need to be replaced more frequently than glass bottles, as they can become scratched and worn over time.

Silicone Baby Bottles

Silicone baby bottles are a newer option on the market, and they are becoming increasingly popular for their durability and ease of use. They are soft and flexible, which can make them more comfortable for babies to use, and they are also often anti-colic, which can help reduce gas and fussiness. The Playtex Baby Nurser, for example, is a popular silicone bottle brand.

Silicone bottles are also easy to clean and can be sterilized in boiling water or in the dishwasher. However, they can be more expensive than other types of bottles, and they may not be as widely available as glass or plastic bottles.

Stainless steel bottles

Stainless steel is highly durable and resistant to damage, which means it won’t shatter if dropped and are less likely to get scratches or cracks compared to plastic bottles. Due to their long-lasting nature, these baby bottles can be a cost-effective choice over time.

One of the significant benefits of stainless steel is its excellent insulating properties, which keep your baby’s milk at a consistent temperature for longer periods.

In terms of safety, it is BPA-free and doesn’t leach any harmful chemicals, making it a safe choice for your baby’s milk. Also, the smooth surface makes them easy to clean and less likely to harbor bacteria.

However, they do have a couple of downsides. Stainless steel bottles can be more expensive upfront than their plastic or glass counterparts. They can also be heavier, which might be an issue for older babies who like to hold their own bottles.

Furthermore, unlike a plastic or glass bottle, you can’t see through stainless steel, so it can be harder to know how much milk is left during feeding.

Bottle Features to Consider

When it comes to choosing the right baby bottle, there are several features to consider:

Venting Systems

Venting systems in baby bottles are designed to reduce the amount of air that a baby ingests while feeding. This can help prevent issues such as colic and gas. There are several types of venting systems available, including straws, valves, and vented nipples. Some bottles also have built-in venting systems that help to regulate airflow.

Size and Shape

The size and shape of a baby bottle can also make a big difference in how well it works for your little one. Smaller bottles may be more suitable for newborns who usually start with smaller 4-ounce bottles and then move onto larger 8 or 9-ounce bottles as the baby’s appetite grows.

Larger bottles may be better for older babies who need more milk. The shape of the feeding bottle can also affect how easy it is to hold and clean.

Narrow-necked bottles tend to be compatible with many breast pumps, which can be a convenience for pumping moms. In contrast, wide necked bottles often come with features like slow flow nipples, which can be easier for a baby to latch onto, especially if they are also breastfeeding.

No matter what type of bottle you choose, it’s important to make sure it is the right size for your baby and that you are using the correct position for bottle-feeding.

Anti-colic bottles can help reduce gas and discomfort in babies who are prone to colic. Bottles with anti-colic features can help reduce the amount of air a baby ingests during feeding, which might help if your baby is suffering from colic or excessive gas.

Ultimately, the right bottle for you and your baby will depend on your individual needs and preferences.


When it comes to the baby’s milk, the type of bottle you choose can sometimes make a difference. Bottle nipples come in different flow rates, from slow flow nipples suitable for newborns to faster flow nipples for older babies.

If your baby prefers a slow flow nipple, you might need to buy a few extra slow flow nipples to have on hand.

A breastfed baby might prefer a bottle nipple design that mimics a mother’s breast. This could help avoid nipple confusion and promote a smoother transition between breast and bottle.

Latex nipples can be an option if your baby is not taking to silicone or other types of nipples. They are softer and more breast-like but can wear out faster than silicone.


Many parents opt for glass bottles (as opposed to plastic) because they are BPA-free and easy to clean. However, they can be heavy and more fragile.

Silicone bottles are a lighter, unbreakable option that can be more comfortable for younger babies to hold.

Stainless steel bottles are durable, safe, and long-lasting, but they are also more expensive. These bottles usually have a wide neck, which makes them easier to clean.


Bisphenol A (BPA) is a chemical that is commonly found in plastic products. While the FDA has deemed BPA safe in small amounts, many parents prefer to use BPA-free bottles to reduce their baby’s exposure to the chemical.

Look for bottles that are labeled as BPA-free if this is a concern for you.

Cleaning and Maintenance

When it comes to breastfeeding, cleaning and maintenance of baby bottles are still important. Here are some tips to keep your baby’s bottles clean and functioning properly.

Washing and Sterilizing

It is recommended to wash your baby’s bottles regularly to maintain hygiene. Use warm soapy water and a bottle brush to clean the inside and outside of the bottle, as well as the nipple and cap. Rinse thoroughly with hot water.

Some parents prefer to sterilize the bottles, especially if the baby is young or has a weakened immune system. Boiling the bottles for 5-10 minutes is one way to sterilize them, or you can use a steam sterilizer. Bottle sterilizers are available to provide an extra layer of cleaning, although they’re not always necessary especially as babies get a bit older.

It might be helpful to have enough bottles to get through a day or two without washing. Check with your pediatrician for their recommendations.

Remember that breast milk can cause stains and odors in the bottles. To remove stains, try soaking the bottles in a solution of equal parts water and vinegar. To remove odors, try soaking the bottles in a solution of baking soda and warm water.

Breast pumps also need to be cleaned and sterilized regularly. Check with the manufacturer’s instructions for proper cleaning and maintenance.

Overall, keeping your breast pump and baby’s bottles clean and in good condition can help prevent gassiness, spit-up, and nipple confusion.

Leaks and Choking Hazards

Check the bottles for leaks before each use. Tighten the cap and nipple securely to avoid leaks. Also, make sure the nipple is the appropriate size for your baby’s age to avoid choking hazards.

Latex nipples can deteriorate over time and should be replaced every 2-3 months. Silicone nipples can last up to 6 months.

Disposable Inserts

Some manufacturers offer disposable inserts that fit inside baby bottles for easy clean-up. These can be convenient, but they can also be costly and generate more waste.

Feeding Tips

Quick Tips for Bottle Feeding

  • Always wash your hands before preparing a bottle.

  • Use clean, filtered water to mix with formula or breast milk.

  • Sterilize bottles and nipples before using them for the first time and after each use.

  • Hold your baby in an upright position while feeding to prevent choking.

  • Don’t force your baby to finish a bottle if they’re full.

  • Always burp your baby after feeding to prevent gas and discomfort.

Feeding Schedule

Newborns need to eat frequently, usually every 2-3 hours. As they grow, they may start to go longer between feedings. It’s important to feed your baby on demand, whenever they show signs of hunger.

Signs of Hunger

Your baby may show signs of hunger by rooting, sucking on their hands, or making smacking noises. Crying is a late sign of hunger, so try to feed your baby before they get too upset.

Positioning and Latching

Make sure your baby is positioned comfortably and securely against your body. Hold your baby close to you, with their head and body in a straight line. Make sure your baby’s mouth is wide open before latching them onto your breast.

Burping and Spit-up

It’s important to burp your baby after feeding to help release any air they may have swallowed. Some babies may spit up a little after feeding, which is normal. You can use a burp cloth to catch any spit-up.

Transition to a Sippy Cup

As your baby grows older, you might introduce sippy cups, a transitional tool before regular cups. You’ll need 1-2 sippy cups to start with, and you can increase the number as your baby gets more comfortable using them.

As your baby grows and starts to transition to a sippy cup, you might want to gradually reduce the number of baby bottles you have on hand.

Special Considerations

Sometimes babies can show signs of bottle refusal, especially if they’re used to breastfeeding. If this is the case, you might need to experiment with different bottle brands, and nipple types, or even use a bottle warmer to mimic the temperature of breast milk.

Remember, every baby is unique, and what works for one baby might not work for another. It’s always a good idea to buy a few different types of bottles and see what your baby prefers before investing in a whole set.

Will a bottle affect my baby’s teeth development?

Yes and no! Giving your baby a bottle can affect your baby’s teeth development if not managed well. Giving a baby a bottle at naptime or bedtime can lead to tooth decay, also known as baby bottle tooth decay. It’s one of the reasons for early dental care to prevent such issues. Be mindful of when and what your baby drinks from a bottle.


When you are in the market for buying baby bottles, it can be difficult to work out how many you will need. As a breastfeeding mom, you might wonder how often you will even bottle feed your baby.

If you’re exclusively breastfeeding, you might only need a couple for emergencies or the occasional break. But if you’re expressing milk or formula feeding, you could need as many as eight bottles a day.

Choosing the right baby bottles is essential for your peace of mind. Glass baby bottles, for instance, are a fantastic choice to avoid exposure to potentially harmful chemicals found in some plastic bottles.

And, of course, maintaining good hygiene is paramount! Always wash your hands before handling bottles, and sterilize them regularly to keep those pesky germs at bay.

Trust yourself – you’re doing a great job! And remember, there’s no harm in asking for help when you need it.

Every baby is unique, and what works for one might not work for another. That’s why it’s best to start with a few bottles and then buy more as needed, rather than stocking up all at once.

Remember, you’re not just a parent; you’re a superhero to your little one. Happy feeding!


Questions? I Have Answers.

Yes, you may need a few bottles even if you are breastfeeding, especially if you plan to express milk or for times when you might not be available to breastfeed.

Not initially. Newborn and young infants typically consume less than 4 oz per feeding. As they grow and their consumption increases, you may need 8 oz bottles.

The amount of breastmilk a baby drinks from a bottle can vary, but generally, it ranges from 1-4 ounces per feeding in the first month, gradually increasing as they grow.

This varies based on the baby’s age and weight. Newborns may only take 1-2 ounces per feeding. By 1-2 months, this usually increases to 3-4 ounces. However, every baby is different, and these amounts can vary. Always consult with a pediatrician for personalized advice.
