Review
A family of four needs roughly 4× the water, food, and medical supplies of a solo kit — plus child-specific items like formula, diapers, or comfort items.
Essential Categories
Water (12 gallons minimum for 72 hours)
Four people × 1 gallon × 3 days = 12 gallons stored, plus portable filters for extended outages.
Food
Ready-to-eat bars, canned goods, and a manual can opener. Include snacks kids will actually eat.
First Aid
A 100+ piece kit handles cuts, burns, and sprains. Add 7-day prescription medications and N95 masks.
Communication
A NOAA weather radio keeps you informed when cell towers fail.
Build vs. Buy
Buy a base kit ($80–150) for containers and basics, then add:
- Extra water containers
- Family-sized first aid refill
- Power bank and charging cables
- Copies of IDs and insurance cards
Storage Tips
- One home kit (shelter-in-place)
- One go-bag per adult (grab-and-go)
- One car kit for commute emergencies
Hurricane Season Add-Ons (August 2026)
If you're building a kit for Atlantic/Gulf coast families, add these on top of the 72-hour baseline:
| Item | Why |
|---|---|
| Waterproof document pouch | Insurance claims start with photos and policy numbers |
| Manual can opener + ready-to-eat food | No-cook meals when power is out 5+ days |
| Extra phone battery (10,000mAh+) | Outages last longer than phone batteries |
| Cash ($200–400 small bills) | ATMs and card readers fail post-storm |
| Work gloves + duct tape | Post-storm cleanup and temporary repairs |

Bottom Line
Start with our three core picks — first aid, water filter, and weather radio — then expand weekly until you hit 72 hours for all four family members.
