An emergency can cut off clean tap water, refrigeration, or your usual formula brand within hours. The fastest way to protect your baby is to write down exactly how your baby eats right now, then match that method to the supplies and safe-water rules below. This worksheet-style guide walks you through both.
Start With How Your Baby Is Fed Right Now
Before you build a supply kit, answer this question honestly: how is your baby getting fed today? Most families fall into one of three groups, and each one needs a different emergency plan.
- Exclusively breastfed at the breast. Your main risks in an emergency are stress, dehydration, and separation from your baby — not a lack of formula.
- Fed pumped breast milk, formula, or both. You depend on clean bottles, safe water, and often electricity or batteries for a pump. This group needs the most preparation.
- Fed only infant formula. Your plan centers on formula supply, safe mixing water, and clean feeding equipment.
Write your answer down now. It determines which checklist items below actually apply to your household.
Build Your Feeding-Method Decision Map
Use this short decision path to find your starting point.
If you breastfeed at the breast: Your emergency kit is small. According to the Centers for Disease Control and Prevention (CDC), a supply of disposable nursing pads is the main item to add, since reusable pads require laundering you may not be able to do. Breastfeeding can safely continue even if you are sick with common illnesses such as the flu, and even if food is limited, though staying hydrated and eating what you can matters for your own health.
If you pump breast milk: Plan for a power outage first. The CDC recommends packing your breast pump and pump kit parts, extra batteries or a power cord, and a manual pump as a backup in case electricity fails. Add a small cooler with ice packs for storing pumped milk, and breast milk storage bags or containers.
If you feed formula, in any amount: Your plan has two parts — the formula itself, and the water it needs, or doesn’t. The next section covers both.
The Safest Formula Choice When Water Is Uncertain
Not all infant formula carries the same risk during an emergency. The CDC identifies ready-to-feed (RTF) formula — liquid formula in sterile, single-use containers that requires no mixing — as the safest option during a disaster, specifically because it removes the water-safety question entirely.
If powdered formula is what you have, the right water step depends on why your water is unsafe:
- Germ contamination (a water main break, storm, or flood): the CDC says you can still use tap water for formula. Boil it, or disinfect it, then let it cool to room temperature before mixing. Bottled water works too and skips that step.
- Chemical or toxin contamination: this is the one situation with no boiling workaround. The CDC states that boiling, disinfecting, or filtering cannot make chemically contaminated water safe. Use bottled water or ready-to-feed formula instead, and follow guidance from your local public health department.
Whichever water you use, follow the label exactly: use the amount of water listed on the formula container, measure the water first, then add the powder. Too much water may not meet your baby’s nutritional needs; too little can make your baby’s kidneys and digestive system work too hard and cause dehydration. Never dilute formula to stretch a short supply.
If your baby is younger than 2 months old, was born prematurely, or has a weakened immune system, take one extra step even outside of an emergency: boil the water, wait about five minutes, then mix it with the powdered formula while it’s still very hot. Let the mixed formula cool before feeding — test a few drops on your wrist so you don’t burn your baby’s mouth. This step kills germs such as Cronobacter, a bacteria that can live in the environment or in dry foods like powdered formula. CDC-tracked Cronobacter infections in infants are rare, but can be serious.
Cleaning Rules That Protect Your Baby
Bottles, nipples, sippy cups, and pacifiers can grow harmful germs quickly if they aren’t cleaned well, and a heat source for sanitizing may not be available during an emergency. The CDC’s cleaning guidance comes down to one rule: if you cannot clean an item with safe water and soap, do not use it.
Two practical steps follow from that rule:
- Keep disposable cups in your kit. They don’t need to be washed between uses, which makes them a safer fallback than reusable bottles when clean water is scarce. A lactation support provider can show you how to cup-feed a baby if you haven’t done it before.
- Discard anything that touches floodwater. Bottle nipples, pacifiers, and other items that are hard to clean thoroughly should be thrown away if they come into contact with floodwater, rather than washed and reused.
The Records You Need Before an Emergency
Supplies solve today’s feeding problem. Records solve tomorrow’s, especially if you’re displaced, separated from your usual pediatrician, or need help from an unfamiliar provider or shelter. Keep these in a waterproof container with the rest of your family’s emergency documents:
- Your child’s medical records, including their vaccination record.
- Your pediatrician’s name and phone number, and the name of any lactation support provider you work with.
- The exact formula brand and type your baby uses, if applicable, so a substitute can be matched as closely as possible.
- A note of any feeding equipment your baby depends on, such as a specialized bottle or feeding tube, so a replacement need can be communicated quickly to responders.
The CDC’s own family emergency checklist also recommends a simple ID tag with your contact information, attached to a diaper bag or carrier — useful if a caregiver becomes separated from a child during a fast-moving evacuation.
Where to Get Individualized Help
This guide explains general planning steps; it is not a substitute for guidance from your baby’s own healthcare provider. Before or during an emergency, individualized help is available from:
- Your pediatrician or family healthcare provider, for questions specific to your baby’s health, feeding history, or any medical conditions.
- A lactation support provider, for hands-on help with cup feeding, relactation, or maintaining a milk supply under stress.
- CDC-INFO, at 800-232-4636, for general public health questions, including infant feeding in emergencies.
- Your local public health department, for water-safety advisories specific to your area during an active emergency.
If you or your baby need emergency medical care, contact local emergency services directly rather than relying on this guide or any written checklist.
Printable Infant Feeding Emergency Checklist
Copy the sections that match your feeding method from the decision map above.
If any breast milk is involved:
- Disposable nursing pads (one to two boxes)
If you pump:
- Breast pump and pump kit parts, plus power cord
- Extra batteries and a manual backup pump
- Small cooler with ice packs
- Breast milk storage bags or containers
If you feed formula:
- Ready-to-feed formula in single-serving containers, when available
- Powdered formula plus a liquid measuring cup and a food-grade mixing container with lid, if RTF isn’t available
- Bottled water for mixing
- Bottles and nipples
For every infant or young child:
- Diapers, wipes, and diaper rash cream
- Disposable cups, dishes, and feeding spoons
- Resealable bags for dirty diapers and clothing
- Wash basin, scrub brush, dish soap, and a mesh drying bag for reusable items
- Bottled water for drinking
- Child’s medical and vaccination records
- Extra clothes and blankets
Keep This Plan Current
Babies grow quickly, and a formula amount that covers several days this month may fall short in two months. Check your kit monthly: confirm formula hasn’t expired, update the quantity for your baby’s current intake, and swap out any records that have changed, such as a new pediatrician or updated vaccination record.
