Unfortunately, you can’t just set it and forget it.
You took the time to assemble the perfect prep kit, so don’t let it sit and collect dust. The only constant in life is change, and your kit needs to reflect changes in your family’s needs.
You should check your kit at least once every 3-6 months. Replace any expired food items, check that all your electronic devices are still in working order, and that all your supplies are in good repair.
When storing your kit, put all food items in a dry, cool place to prevent them from spoiling. Use containers that seal tightly and are made of plastic or metal. Cardboard doesn’t do much against bugs, mice, and dust.
As your needs change, update your kit accordingly. If a new bundle of joy joins the family or you adopt a pet, you’ll need more food and water in your kit.
