Read this article to learn how much formula to mix per ounce in a bottle and how to properly make formula in a bottle.

How many scoops of formula for 4 oz you will need may depend on what brand of formula you are using. Generally, you will need two scoops for a 4 oz bottle. However, you will need to determine how much you need depending on whether or not you are mixing different formulas or mixing to use immediately or to save for later. 

You should be following the preparation instructions on the label for your particular formula. Using too much water can dilute the formula so that it can’t give your baby the nutrition it needs. Using too much formula in water will mean that the formula doesn’t mix properly and will likely result in your baby not wanting to drink it. 

You should only disregard the instructions on the formula’s label if your doctor specifically says so. There could be times when your baby’s nutrition needs to be regulated more closely, or do you need to mix something with the formula and water, which compensates for using less of the powder. Otherwise, your baby’s nutritional needs need to mix enough formula.

Is It One Scoop of Formula Per Ounce?

One scoop of formula does not equal 1 oz of water used. If you have a 2 oz bottle, you will need one scoop of formula, whereas, for 4 oz of water, you will need two scoops of formula. Generally, you should think of it as one scoop for 2 oz, but it’s best to check the label of your specific formula to see the mixing instructions.

One of the issues with measuring a scoop is that some brands have a different measurement depending on which scoop they provide. Generally, it will be 3.5 teaspoons per scoop or about 3 grams in weight. You should check the label to know what counts as a scoop to compensate for that if you lose the scoop that comes with the formula. 

You must follow the directions and measurements on the label, as providing more or less formula than your baby needs for an extended period can cause significant nutritional deficiencies. Scientists have carefully researched the measures to ensure a balance of vitamins, minerals, and nutrients. Failing to get the correct measurements can even lead to developmental problems, strokes, and seizures.

How Do You Make a 4oz Bottle of Formula?

If you have a powdered or concentrated liquid formula, you will have to figure out how to mix it properly together. You should get instructions for your specific formula on the bottle itself, but there are some general rules that most people could follow. It is slightly different depending on what type of 4 you’re using, whether powdered or concentrated. 

Before getting started and mixing your formula, make sure that you are tricking the use-by date on the container so that you don’t use out-of-date formula. Please wash your hands with soap and warm water and ensure to rinse well. Clean any bottles, nipples, and caps you’re going to be using when giving the formula to your baby. 

A quick note on whether or not you’re using bottled water to mix with your formula. You should ask your doctor if your infant will need fluoride drops. You can also get bottled water that already has fluoride in it, which is usually something like “nursery water.”

How to Make Powered Formula

  1. Clean the plastic lid before you open it and write the date on the outside of the lid.
  2. Decide on how many ounces you will make and use the directions on the label to let you know how much formula to water you need.
  3. Add water to the bottle first. You want to make sure that there’s already water in the bottle before you at the formula.
  4. Put the amount of formula you need in the bottle. If you’re making 4 oz, you will need two scoops. Don’t pack the scoop while getting the formula. Make sure that it loosely fits within the scoop. 
  5. Shake the bottle well to mix the formula with the water. However, ensure that you aren’t mixing too much as this can add air bubbles into the formula, which can cause gas. 
  6. Put the formula in the fridge and use it within the next 24 hours.

How to Make Concentrated Formula

  1. Clean the top of the container and shake the container well before opening.
  2. Check the label to see how much mixture you will need to water. Use a measuring cup to pour the water and formula into a clean pitcher. Please do not use the formula container itself for measuring.
  3. Stir the mixture well before pouring it into a clean bottle for feeding.
  4. Put the bottle in the fridge and make sure to use it within the next 24 hours.

How to Store Formula Safely

Once you have made your formulas vital, you know how to store them correctly. You should use the formula within 24 hours after you first make it. Do not add extra water or formula to the mixture, which can impact your baby’s nutritional needs.

If you open a container of concentrated formula or ready-to-feed formula, you don’t have to use it all. Cover the container and put it in the fridge to use within the next two days. Use any open container of powdered formula within the next four weeks. 

When using formula from the fridge, do not want it up in the microwave. This could cause the formula to be heated unevenly, which could result in burning your baby’s mouth. Put the formula from the bottle into a pan of hot water and let it stand for a few minutes. You can also run the bottle under hot water to help the warrants soak into the formula.


You will need about two scoops for a 4 oz bottle. Think of it as if you will need one scoop for every 2 oz to mix the formula with. However, it’s best to read the label on your specific formulas to get the mixing instructions from there, as they may differ from brand to brand.
