How Many Baby Bottles do I Need?

Think about your newborn’s feeding schedule and how often they eat. The number of bottles required may differ based on your baby’s appetite. A newborn will need between 6-8 bottles to ensure a proper feeding routine, with some flexibility based on methods of feeding and cleaning preferences.
On the other hand, those who breastfeed but also offer breast milk in a bottle 4-6 times will need fewer bottles. Newborns usually have 8 to 12 feeds daily, which can vary, so having extra bottles can be handy.
Starting off, it is best to have a couple of bottles and increase them as needed to have a clean backup. If you plan on pumping breast milk and feeding it from a bottle, having at least 4 to 6, including a caregiver’s, is advisable. Your pediatrician’s advice is always helpful.
How Many Bottles Do You Need for Formula Feeding?
The number of bottles required for formula feeding varies depending on your baby’s age and appetite. For formula-fed babies, having anywhere from 10-14 bottles on hand is recommended. Follow the recommended feeding schedule and calculate the number of bottles needed based on your baby’s formula intake per feeding.
If you need extra bottles for convenience or emergencies, keep some on hand. Larger bottles are also available for babies who consume more milk, but it’s important to be cautious about overfeeding.
How Many Bottles Do You Need for Breastfeeding?
Breastfed babies should be introduced to a bottle around 3-4 weeks of age. Start with one bottle and gradually increase as needed. The number of bottles required may vary depending on whether you’re exclusively breastfeeding or supplementing with pumped milk.
Consulting with a lactation consultant can guide on maintaining breastfeeding while introducing bottles. Be flexible and adjust the number of bottles based on your baby’s needs.
Factors to Consider When Choosing Baby Bottles
Choosing a safe baby bottle for you and your child requires consideration of several factors, including the materials used. It is very important to find BPA-free bottles for your baby. The bottle’s material, like silicone or plastic, should also be considered, and you should choose based on your needs and preferences.
Bottle flow rate is another important factor to consider. Choosing bottles with different flow rates ensures they get enough milk without discomfort. Wide-neck bottles are easy to clean and fill, saving time and labor. The bottles you choose need to be durable and be able to withstand frequent use since they will be used every day.
The American Academy of Pediatrics recommends that parents take precautions to reduce their family’s exposure to chemicals in plastics, such as those found in baby bottles.
How Many Bottles Do You Need for Formula Feeding?
The number of bottles required for formula feeding varies depending on your baby’s age and appetite. Having anywhere from 6-8 bottles on hand is recommended for formula-fed babies. Follow the recommended feeding schedule and calculate the number of bottles needed based on your baby’s formula intake per feeding.
If you are intermittently bottle-feeding and are nursing, 2-4 bottles should be enough. Larger bottles are also available for babies who consume more milk, but it’s important to be cautious about overfeeding.
How Many Bottles Does a Baby Need a Day?
Newborns, whether breastfed or formula-fed, typically need to feed 8 to 12 times a day. In the case of formula feeding, this means about 7 to 12 bottle feeds per day for the first few days and weeks.
Cases | Needed Bottles Per Day |
Breastfed babies | 2 – 3 bottles |
Bottle-fed babies with no breastfeeding | 5 – 6 bottles |
Moms expressing breast milk, feeding with bottles | 5 – 6 bottles |
Exclusive pumping (no formula) | 6 – 8 bottles |
Feeding twins | 4 – 6 bottles (if also breastfeeding), 10 – 16 bottles (if only bottle-feeding or exclusive pumping) |
Babies dropped off at daycare | 3 – 4 bottles |
Newborns | 8 bottles in 24 hours |
Babies over two months old | 4 – 5 bottles |
Diaper bag packing | 2 – 3 bottles |
Disposable bottles and liners | 1 – 2 bottles |
Liner use by age: | |
• 0 – 2 months | 8 – 10 liners |
• 2 – 6 months | 5 – 7 liners |
• 6 – 12 months | 3 – 5 liners |
How Many Bottles Do You Need for Breastfeeding?
For breastfeeding parents who plan to use bottles occasionally for expressed breast milk or when someone else is feeding them, a baby having 2 to 4 bottles is generally sufficient. This smaller number reflects the less frequent need for bottles than exclusive bottle feeding.
If you combine breastfeeding with bottle feeding more regularly, such as for expressed milk or formula supplementation, you might want around 3 to 6 bottles to comfortably accommodate feeding and cleaning routines.
The exact number depends on how often you pump and bottle-feed, your cleaning and sterilizing preferences, and your baby’s feeding schedule. Breastfeeding mothers typically need fewer bottles than formula feeders because the baby primarily nurses directly, reducing the number of bottle feeds per day.

Standard Bottles

Standard and classic bottles come in various sizes and materials, such as plastic, glass, or silicone. They usually have a straightforward design and are easy to clean. Standard bottles are a great starting point if you’re looking for simplicity and reliability.
Anti-Colic Bottles

Anti-colic bottles are designed to reduce the air your baby swallows during feeding. They feature special vents or valves that help minimize gas, spit-up, and discomfort. If your baby tends to be gassy or fussy after feeding, these bottles might be worth considering.
Wide-Neck Bottles

Wide-neck bottles have a wider opening, making them easier to clean and fill. They often mimic the shape of a breast, which can be helpful if you combine breastfeeding and bottle-feeding, as it encourages a natural latch.
Specialty Bottles

Specialty bottles are also designed for specific needs, such as angled bottles to reduce neck strain for babies who struggle with certain feeding positions or bottles made from eco-friendly materials for parents who prioritize sustainability.
Tips
As you select the types of bottles to buy, consider your baby’s feeding habits, any sensitivities, and your convenience. Many parents find that having a mix of standard and anti-colic bottles covers most situations, but the choice ultimately depends on what works best for you and your little one.
When to Replace Baby Bottles: Signs of Wear and Tear
Over time, baby bottles can wear down & pose a threat to your baby’s safety. Regularly checking your bottles is crucial to ensure their safety. Remember that plastic crumbling poses threats if bottles cloud over, discolouration begins, or cracks.
Nipples should be checked for stickiness, cracks, irregular shapes, and tearing. Choking hazards can be vacuumed if replaced right away. Despite everything looking “a-okay”, hygiene and safety standards require baby bottles to be replaced every 3-6 months.
New parents are bound to feel peace of mind and safety as replacing bottles and nipples keeps feeding sessions safe.
