How to Make Baby Formula in 3 Easy Steps

Learning how to prepare baby formula is a key skill for many parents and caregivers. We’ll show you how easy it can be in 1-2-3!

Key Takeaways

  • Always start with clean hands and sanitized bottles.
  • Use the exact amount of water and formula as instructed on the label.
  • Never microwave formula—warm it safely by placing the bottle of prepared formula in a bowl of warm water or bottle warmer.
  • Enfamil® offers a variety of clinically tested formulas designed to meet your baby’s needs.

What You Need to Make Baby Formula

  • Clean baby bottles and nipples
  • Bottle caps and rings
  • Formula scoop (comes inside the tub)
  • Safe drinking water (boiled or sterilized if needed)
  • A clean surface and your hands washed with soap and water

Step 1: Wash Your Hands and Sterilize the Bottle

The first step to making baby formula is to wash your hands thoroughly with soap and water. We want to avoid exposing babies, who have developing immune systems, to any unwanted germs. Check the use by date on the container to ensure the formula hasn’t expired. If your container is damaged, dented, bulging, or leaking, call the number listed on the back and do not use it.

And speaking of those germs…you may want to sterilize the bottle with boiling water. Washing bottles with hot water and soap removes germs, but sterilization helps eliminate potentially harmful contaminants and bacteria, providing additional protection for your baby's developing immune system.

Step 2: Measure and Mix Your Baby Formula

Always follow the instructions on the label for measuring and mixing the formula; pour the desired amount of water into the bottle first, then the correct amount of powder.

Using Water for Baby Formula

You’ll want to use room-temperature water. Your container will indicate how much water you’ll need based on how much formula you’re using. Pour desired amount of water into the bottle and add powder per the directions indicated. Powder should be measured with unpacked, level scoops, using the scoop enclosed in the can.

Pour the water first, then the powder. This helps everything mix properly.

“Unpacked and level” means you scoop the powder and then use a clean knife to even it out.

How to Measure Baby Formula

Formula TypeHow to Measure

Liquid ConcentrateCheck the label for the exact formula-to-water ratio.
Powdered FormulaCheck the label for the exact formula-to-water ratio.

Step 3: Shake and Serve!

Make sure the cap is on tight, and shake well. Make sure your formula isn’t too hot by placing a drop on the inside of your wrist. The liquid shouldn’t feel warm or cool—room temperature is perfect.
