How to Make a Baby Bottle: How to Make Baby Formula Steps
- Step 1: Wash your hands
The first step to making baby formula is to wash those hands! Always. Make sure you do it thoroughly with soap and water. You want to avoid any unwanted germs when it comes to making your baby’s formula.
- Step 2: Measure water into bottle, add formula powder
The precise ratio of powder to water varies from formula to formula. Ask your doctor which formula’s best for you and follow the directions on the package. Also ask about using cooled, boiled water for mixing and boiled clean utensils, bottles, and nipples before feeding.
- Step 3: Tighten cap and shake
Mix well, then place a drop on the inside of your wrist to check the temperature. The liquid shouldn’t feel warm or cool—room temperature is perfect. Then it’s ready to serve.

Baby Formula Guidelines
It’s important to pay attention not only to what you are feeding your baby, but also how you feed them. Many new parents wonder, “How long does baby formula last?” and “How do I store formula?” When it comes to formula, there are multiple missteps you can make. Learn how to safely store and prepare baby formula, including powder, concentrate, and ready-to-use baby formula with the guidelines below.
Should you warm formula?
Formula does not need to be warmed. If you want to, place the bottle of prepared formula in a container of warm (not boiling) water, or run it under the warm tap for a little while. Always test formula by placing a drop on your wrist to make sure it isn’t too hot.
Never use a microwave to heat formula. Microwaves can heat liquid unevenly, resulting in hot spots that could seriously burn your baby, and may not be detectable when you test it on your wrist.
Should you add more water to make formula go further?
No. Follow the preparation directions on the package of formula. These amounts of water and formula are designed to provide your baby with the nutrition they need. Adding too much water to powder or adding water to liquid formula can dilute important nutrients.
Can you use bottled or filtered water to make baby formula?
Boiling the water first is safest. However, if you’re traveling with your baby you can use Enfamil® Water, which is commercially sterile and ready to be mixed with formula. If you have concerns about lead or other harmful substances in your tap water, talk to your doctor about viable alternatives.

How do you make formula bottles in advance?
Mix concentrated liquid or powder formula with cool water (35 to 75°F); it should feel cool on your wrist. If you prefer, you may mix with warm water, but only if you plan to feed or refrigerate the formula immediately. Warm water is about 100°F or body temperature; it should feel neutral (neither warm nor cool) on your wrist. Powder should be added to the water and not vice versa since this can make a difference in the formula’s mixability and consistency. If you still have questions about prepping your baby’s bottle, follow the three easy steps above, and it will become second nature in no time.
