Feeding an Infant Without Power or Clean Water
CDC's emergency order of preference — breastfeeding, then ready-to-feed formula — the 2-hour and 1-hour clocks, and why homemade formula hospitalizes babies.
This is for educational purposes only. Not professional medical, electrical, or safety advice.
Warning
Never stretch formula with extra water and never make homemade formula — FDA reports hospitalized infants with low calcium after homemade formula and warns of contamination, missing nutrients and potentially life-threatening imbalance. Never use chemically contaminated water, even after boiling.
- 01
Keep breastfeeding where it is established
CDC describes breastfeeding as the safest emergency feeding option. Breastfeed more often if supply seems reduced and seek help promptly if feeding is ineffective. Exclusively breastfed babies under 6 months do not need additional drinking water, even in hot weather. Secure safe water and food for the caregiver instead of forcing excessive fluid.
- 02
For formula-fed babies, prefer ready-to-feed
CDC identifies sterile liquid ready-to-feed formula as the safest emergency option — and says do not add water to it. Without safe water and soap for cleaning, use appropriate disposable feeding supplies.
- 03
Clean hands, workspace and equipment
Wash hands with soap and safe water; CDC's emergency guidance permits hand sanitizer with at least 60% alcohol when safe handwashing water is unavailable.
- 04
Use safe water and the exact label ratio
Measure the water first, then add the manufacturer's specified powder using its own scoop. Too much water reduces nutrition; too little can cause dehydration and excessive kidney and digestive burden. Germ-contaminated water can be treated — but boiling cannot remove harmful chemical contamination.
- 05
Account for germs in the powder itself
Powdered formula is not sterile. For infants under 2 months, born prematurely, or immunocompromised, CDC instructs boiling water, waiting about 5 minutes, then mixing while very hot — roughly 158°F/70°C — and cooling safely before feeding. Making the water drinkable does not sterilize the powder.
- 06
Respect both clocks
Use prepared formula within 2 hours of preparation and within 1 hour after a feeding begins, and discard what is left after a feed. If it will not be used within two hours, CDC allows immediate refrigeration and use within 24 hours — but that requires reliable refrigeration. Without power, prepare only the amount needed now.
- 07
Clean and sanitize after every use
Disassemble, wash in a dedicated basin with soap and safe water, rinse, and air-dry. CDC's boiling sanitization method is 5 minutes; remove items carefully and air-dry without rinsing again. Sanitizing matters most for very young or immunocompromised infants.
