Nutrition plays a very big role in the proper development of a child, especially in infancy. Expecting parents are very aware of this and that is why they wonder how many times a baby would eat in a day. 

One of the questions that anxious expecting parents always ask is “how many baby bottles do I need to buy?” The answer to this question depends on the age of your newborn, whether or not you make use of formula feeding or if they are breastfed babies, or you use both.

Why Do I Need Baby Bottles in the First Place?

Generally, it is advised to breastfeed your baby during the first six months of their life although it wouldn’t hurt to switch it up with bottle feeding and formulas. So how many bottles do you need to have in hand when your baby is born?

It is quite possible to breastfeed and also bottle feed. Note that the amount of bottles you will need to keep on hand is smaller than when all you do is bottle feed. Before you start giving your babies bottles of formulas, research if it’s age-appropriate and their ingredients to keep your baby safe.

How Many Baby Bottles Do You Need?

If you’re breastfeeding, you will need up to three to four bottles on you while if you’re bottle-feeding it can range from eight to ten bottles. When you’re going out and plan to bottle feed while at it, you need to calculate the hours you’ll be out and take with you the appropriate amount of bottles plus an extra.

Newborn infants are small, they do not require a lot of feeding at one go but they will definitely get hungry in two to three hours so keep the size of the bottle small, say like four to five ounces and increase the number of bottles at hand, like ten to twelve (if you bottle feed). Feedings per day may be from six to eight times. It wouldn’t hurt to have extras laying around.

As your baby grows older, you can increase the size of the bottle and amount of feeding. Six ounces of the bottle should do for a four-month-old baby. The amount of bottle you may need will definitely decrease as the child gets older while the amount of breast milk or formula increases.

At six months and above, your baby can consume about seven to eat ounces per day. At a later age, you might have started introducing some semi-solid food to your babies but it is still advised to breastfeed them up until they are a year old. So during this period, they may only bottle feed three to four times per day.

When Can You Start Pumping?

It is possible for you to pump too early which makes the baby too dependent on bottles or too late, which may lead to them rejecting the bottle. 

Breastfeeding is very important at the early stage of life so it is recommended to wait until they are six weeks old, that is if you will not be separated from the child at any moment. If the reverse is the case, you can start pumping right away and preserve your breast milk until you are reunited with your baby again.

What Are The Different Types of Bottles?

1. Plastic bottles

This type is very common and a favorite of a lot of people. It is light, transparent, and doesn’t cost a lot. Even though this is a great option for feeding, they can carry harmful chemicals such as Bisphenol which is harmful to your baby. Do proper research on this type of bottle before choosing to buy them.

5. Anti-colic

This type of bottle takes into consideration newborns that have gas and colic complications. It is designed in such a way that it reduces the number of bubbles and air the baby takes in, leading to easy digestion. There is a wide variety of brands to choose from. 


  • Aids digestion and fights gas and reflux
  • Reduces the baby’s intake of air and bubbles


  • Can be difficult to clean
  • It’s made up of several parts and components

Types of Nipples

Nipples can be made of silicone or latex. Even though latex nipples are flexible and softer, silicone is preferable because some babies are quite sensitive to latex. Silicone nipples last much longer.

The specific nipple you choose for your baby bottle should be one that fits into your baby’s mouth and enables a moderate flow of milk. The nipple shape also plays a part in proper feeding.

The traditional type of nipple is one that is flattened to mimic a real breast. Another type is the angled one. It is slanted to allow the nipple to enter your baby’s mouth automatically.

Newborns will require a slower flow nipple with a neck not too wide so they can easily suck it. A nipple with a small hole will prevent the infant from gagging and choking. While older babies need wider nipples with faster flows and a wide neck. A hungry baby can get frustrated if the flow of the milk is not very fast, so this is very important.

There are some baby bottles that are anti-colic and come with their own special nipples to prevent the baby from taking in large amounts of air. 

How to Keep Baby Bottle Warm

It is not always necessary to warm your baby bottles. If your baby likes it at room temperature, go ahead and give it to them like that. This method we’re about to give you is not meant for formulas that have been stored in the fridge or have been made hours ago. It is for freshly made formulas. 

You can use electric bottle warmers to heat it up to room temperature. This will take about six minutes. Or you can fill a bowl with warm water and then place the bottle inside for about fifteen minutes. 

Another option is to make your baby formula with warm water and if this isn’t an option, you can just place the bag your breast milk is in and run it under warm tap water, then transfer it to the bottle.

Do not ever warm your bottles in a microwave or stove-tops no matter how busy you are or in a hurry you are. The contents will not get warm evenly and some parts may get hotter than the rest and burn your baby.

Also keep in mind that we are trying to keep the formula warm, not hot so it doesn’t need to be scalding. To test if it’s safe enough for your infant, pour a little bit of the liquid on the back of your hands.

How to Clean Baby Bottles

  • After feeding, separate all the parts of the bottle, including the nipple 
  • Rinse first with cold water and make sure you get the milk or formula stuck in the nipple
  • Use warm soapy water to wash the bottle then run them through warm water to rinse
  • Drain and clean them with a clean towel
  • To sterilize them, soak them in hot water for about five minutes

Note that you do not have to sterilize your bottle after each feed. It is only necessary to do so before the first use. 


If you’ve been wondering “how many baby bottles do I need to buy?”, you can never have too many. Feeding is very essential in your baby’s life so it is great to have a lot of baby bottles in hand but with that being said, you shouldn’t overfeed your baby and force them to eat when they are not hungry. It is important you seek medical advice when your baby is not eating as much as before.
