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.
It's no wonder that all this vivid imagery keeps many preppers preoccupied with civilization-ending events. Some of their worries are based on patently absurd or exaggerated science; some are valid, but rather unlikely to materialize within the span of our lives; and many others boil down to interesting but somewhat idle speculation, devoid of quantifiable risk or historical precedent.
As public institutions deteriorate, élite anxiety has emerged as a gauge of our national predicament. “Why do people who are envied for being so powerful appear to be so afraid?” Johnson asked. “What does that really tell us about our system?” He added, “It’s a very odd thing. You’re basically seeing that the people who’ve been the best at reading the tea leaves—the ones with the most resources, because that’s how they made their money—are now the ones most preparing to pull the rip cord and jump out of the plane.”
More than 160 million American adults (65.45%) are estimated to have either recently purchased survival gear or, interestingly, are already in possession of survival gear because they always keep them on hand. The remaining 85 million (34.55%) are not preparing for the end of the world as we know it. Of those who report prepping, 36.35% spent up to $400 on survival kits in the past 12 months.
These are not your normal cans of beans- these are the big ones. They are the type that many restaurants use, so they are large portions and meant to stack and store. These cans come pre-packaged from many different sources and are one of the best options for food storage. They will not shatter like glass containers and are strong and stackable. They block light, are air tight, and cannot be chewed through easily by rats. All of these attributes make them the go-to for the military. While the cans are not easily reusable, they make a great option for packing away food for long term storage. There is a huge variety of foods available, and most of them taste surprisingly good. Some good vendor that pack #10 cans with some good food include:
One of the biggest obstacles for new preppers is building a stockpile of food and supplies in case of emergencies. Having enough money to reach a critical mass for the stockpile can take years, causing frustration and burnout. To combat this problem, a lot of preppers turn to couponing, and rightly so.  However, a lot of preppers also remain skeptical of couponing.
Finelli sits across from me at the food court picnic table inside the Sam’s Club on Sunshine Street, where he requested we meet. The retired computer systems designer-turned–radio show host and homesteader has salt and pepper hair, wears a plaid shirt and jeans and carries a .45-caliber automatic firearm on his person (he won’t say where). Below his strong jawline hangs a leather bag full of crushed sapphire, meant to enhance his overall health. 
Every year since 1947, the Bulletin of the Atomic Scientists, a magazine founded by members of the Manhattan Project, has gathered a group of Nobel laureates and other luminaries to update the Doomsday Clock, a symbolic gauge of our risk of wrecking civilization. In 1991, as the Cold War was ending, the scientists set the clock to its safest point ever—seventeen minutes to “midnight.”
No heating in the middle of a particularly nasty winter can be problematic, too - although it's mostly a matter of comfort, not survival. In most places, with robust shelter and adequate clothing, bedding, and food, it's fairly hard to freeze to death at home (but note that the cold may make some infections or medical conditions worse; you may have to worry about frozen water pipes, too). The situation can become a lot more dire if you are on foot in the middle of nowhere, so truly hardcore, wilderness-minded preppers may have something to ponder about; but hauling a sufficient amount of fuel is typically impractical to begin with, so their best bet would be warm clothing, improvised shelter, and the ability to build a fire. We'll talk about that in the section that deals with camping supplies.
Restaurants & taxis. Many young, urban-dwelling folks frequently dine at restaurants, go to clubs, or take cabs around town. If that sounds like you, don't give it up, but scale back slightly by designating several days a week strictly for public transport and home food. Contemporary frozen dinners can be surprisingly tasty, and Netflix has some good shows.
If you must take regular medications for a medical condition, you’ll likely want to pack an extra set in your survival kit. You’ll need to discuss the issue with your doctor if you require prescription medications, but don’t forget about over-the-counter medications you may need too. For example, if you often suffer from heartburn, you’ll likely want to add some antacids to your survival kit. Similarly, if you have allergies, you’ll want to pack extra antihistamines, and you may even want to include an EpiPen if an anaphylactic shock is possible.

8. Oats – Another staple, that is super cheap & easy 30 year storage option. Oats are perfect for the prepper because they only require boiled water to prepare, then just add some cinnamon or sugar and you have breakfast. It also helps to control blood sugar and cholesterol. Oats can also double as feed for most animals. Here are 10 reasons you should store oats.
I find surplus ammo cans to be a good storage container with a little work. The large 81mm mortar cans are even capable of holding firearms (Broken down). Most of the cans I get might need some TLC, but making sure the gasket is still intact and usable is a must. I bead blast them to remove any outside and inside rust or corrosion, then repaint them using appliance epoxy (much harder to chip and peel than regular enamel paint).I use several coats (minimum of 3). Depending upon the intended use, I will line the can with 1/2″ closed cell foam. Using a metal can for a Faraday requires some additional work. The top has to be integral to the body. That requires copper tape over the gasket and a ground wire between the can body and lid. I have one can filled with dried rice and beans, that’s been in the ground for 6 years now. I dig it up once a year to check it and it remains bug free and intact still. Metal has one big advantage over the plastic as it is rodent proof. Some very good tips and advice in this column.
Add any extras for your situation: For example, here’s our guide on prepping with food allergies and how to store EpiPens without power. Also consider special needs for pregnant women, small children, pets, people with disabilities or significant medical issues, etc. If you have poor eyesight, always have a pair of backup glasses and contacts in your emergency supplies.
When Survival missions become Nightmare Modes, players will receive both the Nightmare reward and the normal Survival mode reward when completing the mission. Note that even though Nightmare mode enemies are usually higher level, the Survival mode rewards will be based on the mission's original enemy levels. On the other hand, if there is an Alert Survival mission, players will only receive the specified Alert reward (extraction available at 10 minutes).

Honey is one food that never spoils! Although the look of your product will change somewhat over time, it will never actually spoil. It will begin to look yellow and cloudy instead of golden and clear and will get thicker and grainy over time, eventually looking white and hard. But, it is still good. In this form, the honey may have started the process of crystallizing.

This one is pretty obvious, but it stands repeating.  When building a stockpile, you want to stick to items that will be able to last on your shelf.  Items like canned vegetables, canned fruit, jars of peanut butter, jerky, and beans are excellent choices for a stockpile, in addition to household items like toothpaste, soap, conditioner, paper towels, and toilet paper.
One measure of survivalism’s spread is that some people are starting to speak out against it. Max Levchin, a founder of PayPal and of Affirm, a lending startup, told me, “It’s one of the few things about Silicon Valley that I actively dislike—the sense that we are superior giants who move the needle and, even if it’s our own failure, must be spared.”
I can’t emphasize enough that water is key to survival. Living near a lake,stream or river will certainly benefit your survival plans. Also your community will be paramount in overcoming any obstacles you may encounter if things go wonky. Medical knowledge can be found in Red Cross survival books, FEMA has a guide you can download and don’t forget the library or medical schools for info. I’m trying to locate a Grey’s Anatomy book, that and a PDR on pharmaceuticals. These could be a life saver if you had meds and didn’t know how to use them. Thinking outside the box could be your best prepping item.
I suspect nothing much is written (in the MSM) because to do so would mean admitting their global warming/climate change models (scam) have always been wrong (witness the denial of a Minimums effect in the scholarly articles due to ‘it will only counteract the continued [imaginary] global warming effect’). They’ll go on blaming CO2 and global warming even as they freeze – Who knew that ‘Fallen Angels’ was prophetic (and the usual suspects new ‘how to’ book) instead of a fiction?
We liked the Rice Pilaf because it had actual vegetable content! Whole peas and large slices of carrot. No other company has this much vegetable content, not even Mountain House. With chicken broth, white rice, and a surprising addition of orzo, this meal was excellent, especially with some of the freeze-dried chicken included in the Premier bucket.

Astronauts are provided with survival kits due to the difficulty of predicting where a spacecraft will land on its return to earth, especially in the case of an equipment failure. In early US space flights, the kit was optimised for survival at sea; the one provided for John Glenn on the first American space flight in Friendship 7 contained "a life raft, pocket knife, signaling mirror, shark repellent, seawater desalting tablets, sunscreen, soap, first aid kit, and other items".[5] A survival kit was provided for the Apollo program which was "...designed to provide a 48-hour postlanding (water or land) survival capability for three crewmen between 40 degrees North and South latitudes".[6] It contained "a survival radio, a survival light assembly, desalter kits, a machete, sunglasses, water cans, sun lotion, a blanket, a pocket knife, netting and foam pads".[7]
