Babies are the most precious and beautiful things in existence. Taking care of them on the other hand is an arduous task.

You have to be observant of even the smallest details of them because they are just that fragile.

Parenting is not easy and there is much one has to study, learn and be mindful of before they can properly take care of their young ones.

It is one of the few things in life where there is no room for error. No parent ever wants to take any chances when it comes to their child’s wellbeing.

This is especially true when it comes to a child in their developmental years.

One of the most common problems a parent struggles with is making the right mix of baby formula to feed the little one.

Most baby formulas have instructions and safety tips written on them for the correct mixing, proportioning, and storing.

However, there is a lot more to taking care of the baby than simply reading the instructions and following them.

A baby’s immune system is still in its developing stage, it is not capable of fighting and resisting all the bacteria and pathogens that are in the environment.

Moreover, while they are all very cute and deserve all the love and care in the world, not all babies are the same when it comes to their needs and care.

As a parent, you will always want to go the extra mile to keep your child safe and healthy.

Making the baby formula and feeding the baby is perhaps the last step in a long list of things you need to do to prevent your baby from getting sick.

To make it simple for you, we have everything you need to know beforehand to let you provide for your baby in the best way possible.

In this article, how many scoops of formula per Oz? do you need as well as other precautions and tips to keep in mind when taking care of your baby.

Bottle Amount Required Number of Formula Scoops Ounces of Water
1oz of formula 1 (then halve the amount) 2 (then halve the amount)
2oz of formula 1 2
3oz of formula 3 (then halve the amount) 6 (then halve the amount)
4oz of formula 2 4
5oz of formula 2.5 5
6oz of formula 3 6
8oz of formula 4 8
10oz of formula 5 10
20oz of formula 10 20

How Many Scoops of Formula per Oz?

Different volumes of baby formula correspond to the different needs of the baby and you.

The general rule of thumb is to add 1 scoop of formula per 2 Oz of water.

However, such a ratio is only useful for the immediate use of the formula for the baby. Find the right amount, for every purpose below.

1. How Many Scoops Of Formula for 1 Oz

It is unwise to try to add half a scoop of formula to 1 oz of water to make the formula.

This is because it is not easy to add half a scoop and there is much risk of over or under concentrating the formula for the baby.

Instead, it is better to simply add a full scoop to 2oz of water and split it in half. 1oz of the formula is great for preemies since their belly capacity is small and can drink very little at a time.

2. How Many Scoops Of Formula for 2 Oz

As given above, the best method is to add 1 scoop of formula to 2oz of water to make the perfect bottle.

Keep in mind that the scoop should not be tamped down or overflowing. Use a clean knife (or any flat tool) to scrape away the excess powder from the top of the scoop for proper measurement.

A standard 2oz bottle is perfect for your baby’s feeding needs.

Newborns will often drink less than 2oz at a time so start with 1oz and give 2oz if the baby feels hungry.

3. How Many Scoops Of Formula for 3 Oz

Similar to the 1oz problem, it is an unwise risk to try to add half a scoop of formula to the water.

Therefore, you should make a concentrate of 3 oz (Adding 3 scoops to 3oz) and then dilute it with 3oz of water.

Alternatively, you could try to make a 6oz bottle (3 scoops in 6oz) and use half of it.

4. How Many Scoops Of Formula for 4 Oz

Since the required formula volume is an even number, we can add half as many scoops as the volume to get our desired formula bottle.

However, keep in mind that 4oz bottles are too much for an infant to finish in one feeding session.

Thus, it is better to stick to lower volumes to give the baby a fresh bottle every session.

Nevertheless, a healthily growing baby can drink 4oz of formula within a few hours over multiple feeding sessions.

It can be a good idea to use the 4oz bottle if you want to get a few hours of work done.

5. How Many Scoops Of Formula for 5 Oz

Similar to other odd-numbered volumes, the 5oz bottle sits at the awkward position of being too much in volume for a single feed and difficult to add half a scoop for the ideal ratio.

However, because of the increase in volume, there is a larger margin for tolerating error.

Even if you cannot add exactly half a scoop, the surplus or deficit would not affect the overall composition too seriously.

If you don’t want to take the risk. make a 6oz bottle instead.

6. How Many Scoops Of Formula for 6 Oz

The formula still stands for 6oz bottles. Add 3 regular scoops into the water and shake it well.

6oz bottles are great for babies, especially late-blooming toddlers, with a great appetite. Infants can drink up to 24oz a day, a 6oz bottle can last your entire afternoon.

7. How Many Scoops Of Formula for 8 Oz

Now, we are entering the storage volume levels. There are two methods of preparation from here on; it depends on how long you plan to store the formula.

If you plan on storing the formula ahead of time for the entire day, make 8oz concentrate (8 scoops in 8oz) and dilute it at a 1:1 ratio (1oz extra water in the 1oz concentrate) to feed your baby.

Alternatively, you can follow the 1 Scoop per 2oz ratio to make and store a lot of baby formula at once.

However, you will have to constantly reheat the formula which can drastically reduce the freshness and accelerate the rate at which the feed expires.

8. How Many Scoops Of Formula for 10 Oz

Similar to the 8Oz strategy, you can make the formula concentrate on storage and long-term use.

You can also just add 5 scoops in 10oz of water and use them for the entire day.

Nevertheless, it is not recommended to make an excessive formula at once.

While the formula will not go bad if refrigerated properly, there is still a risk of spoiling with constant storage.

9. How Many Scoops Of Formula for 20 Oz

Maybe you need to feed multiple kids and want to make the formula en masse.

For making 20oz of baby formula, follow the golden ratio of 1 scoop per 2oz, for a total of 10 scoops.

Storing baby formula in such large quantities is a bad idea and is discouraged.

An infant usually requires at least 24oz of formula a day between the ages of 9 months to 1 year for proper growth.

However, you should not put the freshness of the formula and the baby’s health at risk for your convenience.

Hygiene

How Many Scoops of Formula per Oz?

Cleanliness is holiness; this could not be truer when it comes to taking care of your baby.

A child’s immune system continues to develop until the age of 8 years old. However, the most crucial development in the immune system occurs in the first 4 months of the baby’s life.

That is not to say that the baby’s immune system is completely unprotected.

The baby’s body inherits its mother’s antibodies to fight off any disease or infections in the first few weeks.

The most vulnerable period in a baby’s life comes in between the first few weeks and then 4 months of age.

Therefore, during this period, there should be extra care for hygiene and sterilization of everything related to the baby.

Some common hygiene tips are:

  • Sterilize the baby’s bottles, bottle caps, and nipple in boiling water for at least 5 minutes before use. When removing the bottle from the boiling water, use a clean pair of tongs to prevent recontamination risk. Getting a bottle sterilizer can make your life a lot easier. 
  • Sanitize or wash your hands before touching the baby or the bottle. 
  • Try to keep the baby in clean warm clothes during the first few weeks and clean them properly after use. 
  • Clean any surfaces that the baby, you, or the bottle may touch beforehand. 
  • Wash the bottle thoroughly and scrape the inside with a bottlebrush before sterilizing it.

While some of this may seem lovely cautious, it isn’t for the reasons we mentioned.

If a one-month-old baby and a one-year-old got the same bug, it would be much more serious for the little baby and would most likely require a hospital visit. 

The Proper Way To Make The Formula

The preparation method for the baby formula is often written on the pack of the formula.

Nevertheless, some standard practices should be followed for the best mix. Let’s take it one step at a time.

1. Choosing the right formula

This can be very difficult as they all look the same so how do you know which one is best?

It’s a good idea to do a little bit of research to check if the formula you’re looking at is highly rated or not.

You can also ask other parents what they use and get recommendations.

If your baby has a lot of spit up then they may have gastroesophageal reflux disease (GERD) or colic.

In these instances, you may want to opt for a thicker formula. If so, you’ll need to get an appropriate bottle nipple.

This thickened formula is also harder to mix, which is important to bear in mind.

If you prefer organic products, then you’ll also find that there are plenty of organic formulas available.

The only word of warning here is that they are often a little more expensive and also harder to source than other types of formula. 

For most parents, they’ll go with a popular and highly-rated formula. If you don’t think your child is taking it well, then you can always switch to a new brand.

While this can be done, it’s worth noting that you should always try and stick to the same formula as a change may take a while for your baby to fully adapt to. 

2. Opening the formula pack

Most baby formula packs are made of metal tins; you can slip a knife under the lid to open it with some leverage.

Before you start using the formula, make sure it hasn’t gone bad. Peek and make sure there is no mold or discoloration in the powder.

If you are living in the US, any commercially produced formulas go through a stringent FDA screening process before approval.

This ensures the quality and safety of the formula for your baby.

3. Prepare the right temperature

Babies are full of personality and individuality from their first day. A sign of this is whether your baby prefers warm formula or cold.

Babies do have a preference and it is mostly what they are accustomed to, if you have been using warm baby formula, the baby will prefer a warm bottle and might even refuse a cold bottle in protest!

Nevertheless, it is safe to feed your baby cold formula in most cases and it can even make your life easier.

However, if your baby is a preemie, you should use a warm formula to help with digestion.

Feeding cold formula to a baby with low birth weight can lower their internal temperatures and cause complications.

When it comes to warming the milk, the simplest way to use is the wrist test.

Place a drop onto your wrist, if it feels too hot, it probably is too hot for the baby too.

While a cold bottle is fine, it does need to be sterilized, which is almost always done with hot water.

Therefore, it’ll make your life easier to feed your baby warm bottles instead of waiting for them to get cold. 

4. Pour water first, formula last

Mixing the formula is important; there are many different kinds of preparation methods for baby formula, such as mixing breastmilk with formula, using formula concentrate to prepare the bottle, and so on.

If you’re scooping powder then it’s best to add it after you’ve poured in the hot water.

This will more effectively sterilize the powder and you’ll also find it easier to mix.

You don’t want to end up with any clumps of powder within the milk.

Before preparing the bottle, it’s always a good idea to wash your hands first to get rid of any bacteria that may be on there.

It’s also good to have sterile surfaces on which you’ll be placing the different parts of the bottle.

There are some great formula machines now which can do this whole process for you but they are quite expensive.

If making yours with hot water, then you can cool it down by placing the hot bottle in cold tap water until it cools down. 

5. Use of cow’s milk

Do not use cow’s milk or other commercially available milk as the solvent for the baby formula or as an alternative to the formula.

The nutritional constitution of cows and commercial milk is unhealthy for the baby and mixing them can give your baby an upset stomach.

However, you can start mixing a bit of cow’s milk with a regular bottle of formula to wean your baby off the formula.

You can start with 1.8oz of formula with 0.2oz of milk and then gradually increase the milk concentration until there is only cow milk being used.

Only begin such training on infants over the age of six months, after consultation with your pediatrician.

Preparing Different Types of Formula

Here are tips for preparing different types of formulas:

1. Powder

Usually, this type of formula is prepared using 1 scoop of powder for 2 fluid ounces of water. Here is the procedure:

  • Add Pre-Measured Water to the Bottle First. 

Of course, this will depend on the oz of prepared formula you want. For instance, for 1 scoop of formula, you need 2 ounces of water to make 2 oz of prepared formula.

If you use 2 scoops of formula, you will need 4 ounces of water, giving you 4 oz of prepared formula. 3 scoops will need 6 ounces of water to give 6 oz of prepared formula.

It is advisable to use hot water to kill harmful bacteria that may be present in powdered formula.

  • Add Formula to the Bottle 

When measuring the formula, slightly tap the scoop to even it out. This helps to ensure that it is not overflowing or packed down.

  • Cap the Bottle and Shake

Shake the bottle gently until the mixture is well mixed. You can choose to mix one bottle at a time or mix formula that you will feed your baby the entire day.

In this case, you can refrigerate it for up to 24 hours. Always test the temperature on your wrist to ensure that it is warm and not hot.

NB: Since the powdered formula is not sterile, it should not be fed to infants with immune problems or those that are premature.

You can consult your doctor about this.

2. Liquid Concentrate

If you use a liquid concentrate, you will need to mix it with water.

For this one, you will need 1 ounce of liquid concentrate for every 1 ounce of water and shake gently.

  • Wash and dry the top of the can before opening.
  • Gently shake the can before opening it with a can opener.
  • Pour the concentrated formula into a bottle. If you want to make a 4-ounce bottle, you will need 2 ounces of liquid concentrate infant formula and 2 ounces water.
  • Add water and shake the bottle well. Also, the mixture should be warm and not hot.
  • Feed the baby immediately or refrigerate the bottle for use within 24 hours.

This will give you a 2-ounce bottle. Like the powered version, you can mix one bottle at a time or mix the concentrate for use in a day or two.

Refrigerate it and ensure that you use it within 48 hours.

3. Ready-to-Feed

This is simple to use and you won’t need to measure or mix the formula.

You just need to pour it into your baby bottle and you will be good to go. You can then refrigerate the unused formula for 48 hours.

The formula is available in 2, 6, or 8 fluid ounce containers.

 

Stages of Baby Development 

Stages of Baby Development 

The baby has three main stages of development. As the baby grows older, the nutrition requirement and how often you need to feed the baby change.

The three stages are Neonatal (Newborn), Infant, and Toddler.

1. Neonatal (Newborn)

Babies are in the neonatal stage for the first four weeks after birth. Newborn babies are sensitive to stimuli and actively respond to them.

For example, the newborn will hold onto your finger if you put it in their hands, turn their cheeks towards your hand if you touch them, recognize smells and respond with crying or smiling.

The neonatal stage is where the genetic disorders and fetal-alcohol syndrome become apparent.

The newborn stage is very fragile and requires extra care in every detail.

According to medical literature, the newborn baby stage has the highest mortality rate.

During the newborn stage the baby’s body is rapidly developing, this includes its digestive tract.

Therefore, the newborn baby needs to be fed more often in small portions to keep up with its nutritional requirement.  

2. Infant

The infant stage starts after the newborn stage and lasts up to one year of age. A baby nearly triples its weight during the first four months after birth.

This healthy growth is also accompanied by a properly developed digestive tract.

This means that the baby can take in more food at once and there is more time in between feedings.

At this stage of life, the baby learns to sit up straight, stand with some support, and learns to call you ‘mama’ or ‘dada’.

Infants can start eating solid foods in small quantities after six months of age when you can start weaning the baby off the formula slowly.

3. Toddler

Your child is a toddler between one and four years of age. A toddler can begin to form a habit of eating solid foods.

It is important to stop feeding baby formula to toddlers, as the formula does not fulfill all their nutritional needs.

However, in case of some food allergies or underdeveloped digestive tract because of some growth problem, the toddler can be given the baby formula until the problem is resolved.

A toddler is capable of standing, walking, and even hopping.

In the toddler stage, babies develop their motor functions, and speech and can begin to be potty trained.  

4. Premature (Preemies)

Babies born prematurely (before 37 weeks of pregnancy) require special care and diets for their growth.

The organs of a prematurely born baby have not completely formed and grown. 

Therefore, their bodies spend much energy and nutrients to catch up in growth.

Consequently, a prematurely born baby’s metabolism rate is extremely high.

To facilitate the baby in this growth spurt, there are special baby formulas made for feeding premature babies.

It has a high concentration of protein, minerals, and vitamins to help the baby grow without issues.

There are many commercially available baby formulas for premature babies, you should ask your pediatrician for the right concentration and brand for your baby’s stage.
