Infants Change Everything

Preparedness planning that doesn't specifically account for infants will fail infants. The general supplies that sustain adults — stored grains, water tablets, basic first aid kits — don't address most of what an infant needs to survive and thrive. An infant needs formula or breastfeeding support, diapers, age-appropriate medications, temperature-appropriate clothing, and caregiving infrastructure that no adult can go without for 72 hours.

The stakes are higher with infants because the timeline to serious consequences is shorter. An infant who goes without adequate nutrition for 24-36 hours is in medical danger. An infant who develops a fever in a grid-down scenario without access to fever reducers becomes a serious medical situation quickly. Adults have far more physiological reserve than infants.


Infant Feeding: The Critical Variable

Formula-Fed Infants

Formula is the highest-priority supply for formula-fed infants. No substitute exists. Cow's milk is not nutritionally adequate for infants under 12 months and can cause renal strain. Homemade formulas are dangerous. The only safe option is commercial infant formula or breast milk.

What to store:

| Formula Type | Shelf Life | Water Required | Notes | |-------------|-----------|----------------|-------| | Powdered (sealed can) | 1 year from manufacture | Yes — safe water | Most economical, lightest to store | | Concentrated liquid (sealed can) | 1 year from manufacture | Yes, 1:1 dilution | Good middle option | | Ready-to-feed (sealed can/bottle) | 1 year from manufacture | No | Most expensive; ideal for go bags or water-scarce emergencies |

Quantities: A typical formula-fed infant consumes 24-32 oz per day in the first weeks, increasing with age. A 2.5 lb can of powdered formula makes approximately 200 oz of prepared formula. For a 30-day supply, you need approximately 3-4 standard 2.5 lb cans (the actual amount varies by brand and infant age/size).

Rotation. Formula has a use-by date. Use the oldest supply first, replace it, and date every can when purchased. A common approach: buy two extra cans when restocking, rotate them into regular use, always maintaining the buffer.

Water for preparation. Ready-to-feed formula requires no water and is the most resilient option when safe water is uncertain. If using powdered formula, water safety is critical — infant immune systems are not equipped to handle the pathogens that adults might tolerate.

Breastfed Infants

Breastfeeding is inherently more resilient than formula feeding in emergencies — no supplies required. But emergencies can affect breastfeeding in several ways:

  • Maternal stress can temporarily reduce milk production
  • Dehydration in the mother reduces supply
  • Separation from the infant (evacuation scenarios) can cause supply disruption
  • Medical emergencies requiring medication may temporarily interrupt breastfeeding

A breastfeeding mother's emergency kit needs additional water allocation (she needs more than non-breastfeeding adults — roughly 13 cups per day instead of 8), adequate calorie stores (breastfeeding burns 400-500 additional calories per day), and a plan for what to do if supply drops (stress reduction, continued feeding frequency, adequate hydration and calories).

Manual breast pump. Battery-operated or manual breast pumps that don't require a power outlet are important if the mother needs to express milk or maintain supply during separation. A manual pump and several storage bags/bottles are worth including in an emergency kit.


Diapers and Diapering

Disposable Diapers

An infant goes through 8-12 diapers per day in early infancy, tapering to 6-8 for older babies. For a 30-day supply:

  • Newborn (0-10 lbs): approximately 240-360 diapers
  • Size 1 (8-14 lbs): approximately 200-300 diapers
  • Size 2 (12-18 lbs): approximately 180-250 diapers
  • Size 3 (16-28 lbs): approximately 160-240 diapers

Diapers don't expire if stored in the original sealed packaging and protected from moisture and extreme heat. They can compress, which may affect fit, but they remain functional indefinitely.

The sizing problem. Infants grow through diaper sizes quickly. Stock the current size and the next size up. Diapers that are slightly too large are functional; diapers that are too small are not. Overstock the next size rather than the current size.

Cloth Diapers

In grid-down scenarios, cloth diapers become essential backup. A disposable supply runs out; cloth diapers, if you have them and the water to wash them, don't.

A functional cloth diaper system requires:

  • 24-36 cloth diapers (for washing rotation without running out)
  • Waterproof covers (6-8)
  • Diaper pins or Snappis
  • Waterproof wet bags for storage
  • A washing method that works without a machine (hand washing in a bucket, wring, line dry)

Cloth diapers require water and the ability to sanitize, but they're indefinitely sustainable with those inputs. Many preparedness-oriented families use both, keeping a disposable supply and cloth as backup.

Diaper Rash Supplies

Diaper rash becomes more likely in emergency situations where changing frequency may be reduced and skin can't breathe normally. Stock:

  • Zinc oxide diaper cream (thick paste like Desitin or A+D — the active ingredient is zinc oxide, which protects and heals)
  • Baby wipes (unscented), or rinse bottles for water washing
  • Cornstarch powder as an alternative barrier

Medications and Medical Supplies

Fever management:

  • Infant acetaminophen (Tylenol Infants') — for infants 2+ months. Check dosing by weight, not age.
  • Infant ibuprofen (Motrin Infants') — for infants 6+ months only. Do not use under 6 months.
  • Rectal thermometer (most accurate for infants under 3 months)
  • Axillary (armpit) thermometer as alternative

Gastrointestinal:

  • Oral rehydration salts (ORS) — for diarrhea or vomiting with fluid loss. Pedialyte packets or Hydralyte. Critical because infant dehydration can become dangerous within hours.
  • Simethicone gas drops (Mylicon) — for gas and colic if infant currently uses them
  • Gripe water — for general fussiness, some infants respond to this

Respiratory:

  • Saline nasal drops — for congestion, safe at any age
  • Bulb syringe or NoseFrida for nasal clearing
  • Cool-mist humidifier (battery-powered or none) if the infant currently uses one

Skin:

  • Fragrance-free baby lotion (many infants with eczema require regular moisturizing)
  • Aquaphor or similar for severe dry skin or skin barrier issues

Prescription medications: Maintain a minimum 30-day supply of any prescribed medication. Have the prescribing doctor's contact information and the pharmacy's phone number readily accessible. Know the generic name of each medication in case brand-name supply is limited.


Feeding Equipment

Beyond formula and breastfeeding supplies, infants need specific feeding equipment:

Under 6 months:

  • Multiple bottles (4-6 minimum) in appropriate nipple sizes for infant age
  • Bottle brush for cleaning
  • Bottle sterilizer (or know how to boil-sterilize in a pot)
  • Extra nipples in the correct flow rate

4-6 months and older (starting solids):

  • Baby food (commercial pureed food in sealed jars — shelf stable for 2 years or more)
  • Soft-tip spoons
  • Appropriate size sippy cups if starting cup

For go bags specifically: Ready-to-feed formula in single-use bottles (no preparation required), pre-sterilized disposable bottle nipples, and baby food pouches (no spoon required) are the most practical options when mobility and minimal preparation are the priority.


Temperature Management

Infants cannot regulate body temperature effectively. They become hypothermic in cold faster than adults and overheat in heat faster than adults.

Cold weather supplies:

  • Warm base layers (fleece or wool onesies, not cotton)
  • Warm outer layers sized for the current infant
  • Hats (infants lose a disproportionate amount of heat through their heads)
  • Blankets — fleece or wool, not just cotton

Hot weather:

  • Sunscreen (SPF 30+, zinc oxide based for infants under 6 months — chemical sunscreens not recommended for young infants)
  • Shade provision
  • Extra hydration monitoring (breastfed infants may need more frequent feeds; formula-fed may need slightly more formula)
  • Cool wet cloths for temperature management

The Go Bag for Infants

The household go bag needs a dedicated infant section or a separate infant go bag. For a 72-hour evacuation:

  • 3-day formula supply (ready-to-feed for evacuation) + 2 extra days
  • Diapers: 35-40 for the evacuation period
  • Baby wipes: 1-2 full packs
  • One change of complete clothing per day + 2 extras
  • Weather-appropriate outer layers
  • Acetaminophen, ibuprofen (if age-appropriate), thermometer, ORS
  • 1 bottle + nipples
  • Comfort items: 1-2 familiar small toys, pacifier if used
  • Copy of birth certificate and insurance cards
  • Pediatrician contact information and vaccination records

The bag should be accessible within 30 seconds. Review and update it monthly as the infant grows through sizes.

Frequently Asked Questions

How much formula should I stockpile?

The American Academy of Pediatrics recommends a 1-2 week supply for formula-fed infants under normal circumstances. For preparedness, a 30-day supply is appropriate as a minimum, with 60-90 days recommended for serious preparedness. Powdered formula has a shelf life of approximately 1 year from manufacture (check the 'use by' date) and requires only water to prepare. Ready-to-feed formula in sealed cans has the longest shelf life and requires no water preparation.

What if I can't get formula in an emergency?

This is why breastfeeding continuation is the most resilient infant feeding option in emergencies. For formula-fed infants, stock a minimum 30-day supply. Have a plan for where to obtain more — contact info for local WIC offices, food banks, hospital social workers. Homemade formula is dangerous; the nutritional gaps cause harm. Cow's milk is not safe for infants under 12 months. Know your options before you need them.

Do infants need any special medications in an emergency kit?

At minimum: infant acetaminophen (liquid, correct age range), infant ibuprofen (6 months and older), oral rehydration salts, and any prescription medications specific to the infant. Teething medications, saline nasal drops, and gas drops are worth including if currently used. Every medication should be in appropriate infant dosing and checked against current dosing guidelines.
