I would add just a few things though, if you use creamer in your coffee add a few bottles of the powdered version, some dried fruits or a couple large bags of trail mix, pie fillings in a few fruit varieties (awesome in oats!), crackers are great for kids who won’t eat a tuna, spam or other canned meat sandwich but they may be willing to eat “lunchables” DIY of course!, and other all in one items like spaghetti O’s, canned stew, canned ravioli, and ramen. It may not be the healthiest solutions but if you need these items you will be exceptionally grateful you have them!
I hope this makes sense to you. It sounds like you have already figured out that with a growing teen and two additional children in the household, this will be a good start but that more will be needed over time. By doubling these quantities my guess is that you will be better prepared, food wise, than 90% of the population. And even without doubling the quantities, you will be better prepared.
Probably one of the very first things you have ever heard about prepping is that you have to store away large quantities of food. This needs to be prepper food that can be stored away for the long-term, perhaps enough food to last for six months to a year or longer. But what kind of food is this? Have you ever wondered if there is specialty prepper food? The answer to this question is yes and no. Confused? It’s actually more straightforward than it might seem.
We as humans tend to be an angry species nowadays. When I was younger arguments were settled with fists, sticks and stones, or perhaps knives as a last resort? Mortality rates from these encounters weren’t as bad as firing a firearm in anger. I’m just afraid my own anger would cause me to fire first! Combat situations are easy to talk bravodo about but unless you’ve ever killed a live person or had another person shoot at you, you have no idea what you would actually do in a grid down situation.
There is one important aspect of planning your freeze dried food storage: try some sample meals before you invest in a six month or one year supply of one particular brand. I have my own preferences that you are welcome to use as a guideline (check out Mountain House or Legacy Foods) but there are others. Also keep in mind that some kits are chock full of sugary drinks and other fillers. Yes, you will need some beverages but they should not comprise 40% of your daily caloric intake.
