Formula Preparation for Your Baby

Here are some basic steps to follow to safely prepare formula for your baby. 
  • Wash your hands prior to making formula.
  • Always wash the top of the formula can before opening it.
  • Clean or sterilize the bottles and nipples before the first use according to the package directions.
  • Wash all bottle pieces and measuring utensils in hot soapy water before using. Rinse thoroughly and let air dry. 
  • Be sure to use the appropriate measuring cups. Cups that measure dry ingredients like powders are different than liquid measuring cups.
  • Check with your healthcare professional or local health department about the need to boil the water you'll use to prepare formula.
  • If water must be boiled, heat water until it reaches a rolling boil, continue for one to two minutes and let it cool thoroughly before using it to mix formula.
  • Follow formula mixing instructions on the can, unless you have been instructed otherwise by a healthcare professional and then mix according to instructions provided to you. 
  • Keep prepared formula in a clean jug in the refrigerator.
  • Formula doesn't need to be warmed, but if you decide to warm a bottle, hold under running water or place in a cup of hot water for a minute or two. NEVER microwave a bottle as the formula can heat unevenly and burn your baby's mouth.
  • Throw out any unused formula left in a bottle after feeding or which has been unrefrigerated for one hour or more.
  • Prepared formula is usually good for 24-48 hours when refrigerated. Check mixing instructions on the can or those given to you by a healthcare professional.
