If this particular calamity strikes, what's the step-by-step playbook you would follow, and how much time would you have to carry out the plan? Will you be sheltering at home, or is this a situation where you need to evacuate? If the answer is "it depends", what would be the key factors, and how quickly would you need to make the final call? If you pick the wrong option, how bad would it be?
Pepper spray. An excellent, temporarily incapacitating weapon - very difficult to resist and capable of buying you just enough time to escape. Works quickly and reliably at distances up to perhaps 10 feet; can also stop some animal attacks. Usually not heavily regulated, making it easy to obtain and carry even in places that frown upon other forms of armed self-defense (but check the laws). Pepper spray becomes less effective in strong wind; there is also some risk of blowback, but this is mitigated in narrow-stream products, such as Sabre Pepper Gel ($18).

Of course, some "doomsday" preppers worry about even more exotic, post-apocalyptic scenarios mentioned in section 2.3, basically aiming for indefinite self-sufficiency. I don't think it's a particularly sound concern, but if the prospect of a civilizational collapse keeps you up at night, my best advice is to move to a rural community where you could farm, fish, or hunt. Some urban survivalists fantasize about trapping local squirrels, pigeons, or raccoons - but they would run out of food very fast. Small urban and suburban gardens are usually difficult to maintain and don't produce enough to feed a family, too.
This brings us to the "how". In most cases, the absolute minimum water intake is somewhere around one quart per person per day; but note that this assumes no weather extremes, no substantial exertion, and no immediate hygiene needs. When these assumptions hold true, storing about 1.5 to 2 gallons per household member - enough for perhaps up to a week - should provide a viable if modest buffer for short-term emergencies. Store-bought gallon jugs are pretty cheap, hassle-free, and easy to squeeze in just about anywhere; if you keep them away from sunlight and heat, they should last 5+ years before needing to be rotated or thrown out. Don't try to save a buck by reusing milk or juice jugs, though: they are almost impossible to clean properly and may end up supporting bacterial growth.
When the average person thinks about doomsday preppers, they probably think of paranoid right-leaning wing nuts clinging to a small arsenal of guns and stockpiling toilet paper from Walmart in case their conspiracy theories come true. It's a fair assumption — many television depictions reflect that mind-set, though the fears vary from group to group. Some are afraid of government collapse, others fear a solar flare, still others are preparing for a race war they think is inevitable. When those are the dominant examples, it's easy to dismiss the practice as absurd and hysterical.
Fear of disaster is healthy if it spurs action to prevent it. But élite survivalism is not a step toward prevention; it is an act of withdrawal. Philanthropy in America is still three times as large, as a share of G.D.P., as philanthropy in the next closest country, the United Kingdom. But it is now accompanied by a gesture of surrender, a quiet disinvestment by some of America’s most successful and powerful people. Faced with evidence of frailty in the American project, in the institutions and norms from which they have benefitted, some are permitting themselves to imagine failure. It is a gilded despair.
I used to focus only on preparing for earthquakes and other natural disasters. That changed in 2011 when I went to my first protest, an Occupy Oakland action, with a medic bag. I didn't know yet that I'd be out there for hours, so I didn't have supplies I consider basic now — food, caffeine, extra smokes, insoles for my combat boots. I didn't know how aggressive the police would be, and the handkerchief around my neck was more for a punk look than medical necessity. I hadn't received formal training to be a street medic; I just happened to know first aid and CPR and wanted to help. I carried a 15-pound bag on my back, full of medical supplies, mainly gauze and tape but also things like tourniquets that I hoped I wouldn't have to use. I was scared — I'd had rubber bullets shot at me the night before — but I was determined to drop off water to the protesters and make sure that people had sterile supplies.
This is true, Kat. Babe, it doesn’t even need to be a true crisis… There are lots of times your stash will come in handy. Unexpected company. Your kid telling you the night before the bake sale that he needs 3 dozen brownies to take to school the next morning. You get out of work late and are too tired to make a grocery run. Everyone in the family gets the flu and you can’t get to the store. The list goes on but the point is that you should be rotating, using and enjoying your stash as part of normal living. A cookbook you might find useful is “The Prepper’s Cookbook” by Tess Pennington. Lots of ideas for setting up your base stash and great recipes too.
63. Snake bit kit – depending on where you live, not a necessity. But if your out about in the country especially in the southern half of the US, having a snake bit kit is wise. Here is a list of venomous snakes by state. These kits usually ome with a powerful suction extractor that can double for any poisonous bite or sting. Here is a decent snake kit.
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.
No flour/wheat because you need yeast, etc? Not completely true. If you have access to clean water (or milk/yoghurt), you can make Indian flat bread or chapattis! Once you get the hang of making them – basically adding tepid water to the flour until you can make a smooth and elastic dough, then roll it out and cook in a skillet – you can make endless variations! I often dissolve a vegetable or beef bouillon cube (you should stock those too, or instant bouillon) in the water first to add more flavor to the chapattis, but you can use any herbs you like. Getting the hang of making them might seem a little trying at first, but eventually whipping them up is just a breeze! My kids love eating them right out of the pan with a little butter spread on the still hot bread, and we often eat them together with beans, etc. Here’s a handy tutorial for those interested: //indianfood.about.com/od/breadrecipes/ig/How-to-Make-Chapatis/Making-Chapatis—Step-1.htm
Flashlights. Unless you are living in a rural area, you don't need an eye-searing torch that chews through ten boxes of batteries in a day. Get two small, high-quality AA flashlights that give you at least 20 hours on low power; keep one near your bed, and another in your car or in an emergency stash. For a low-cost option, try Fenix E12 ($25). If you want 100+ hours of battery life and don't mind the price tag, check out Fenix LD22 ($55).
For powering more serious electrical equipment, a generator is a popular choice for people living in the backwoods. That said, this option comes with an interesting trade-off: if you were ever to face a contingency that may last for a longer while, it may be more important to conserve fuel for driving, cooking, or heating, than to use it for keeping the lights on. A fully-fledged solar installation helps you avoid such dilemmas, but costs an arm and a leg. A possible compromise is a jury-rigged solar setup done at a smaller scale: if you hook up 100W panel ($160) to a deep-cycle lead-acid battery ($60) and a low-cost inverter ($30), you gain the ability to recharge laptops and phones, or even power several desk lamps, a decent-size fan, or a small refrigerator. The whole contraption costs around $250 and is easy to stow away if you're not very short on space.
The survivalist hard-on (yep, and I'll do it again, too) for prophylactics untouched by chemical pleasure-enhancers is the result of drilling deep (told you) into the magical properties of our latex friends. According to our research, these flexible, durable, waterproof wonders will be as much of a deciding factor in your dystopian longevity as fire and can openers.

A three months+ disaster means a lot of bad things will happen. Since most people won’t last for more than 3 weeks without food, the ones that do probably have a lot of power: guns, ammo, food, communications, physical strength and so on. These people are going to be more dangerous, than your typical unarmed zombie begging for food, because they know exactly swhat they’re doing.
Amid the localized terror, trains will deliver the nation’s hapless coastal residents to our doorstep. Pense thinks it’ll look like the Holocaust, that the government will deposit boxcars of starving New Yorkers and Californians into the suddenly crowded Heartland. Then they’ll go back for more. It’s going to be, Pense says, some interesting times. 
Growing your own fruits and vegetables is a slow and gradual process, requiring at least one growing season and one harvesting season. Approach this in a smart way by purchasing a packet of seasonally relevant seeds when you first begin, which can be as little as $1. Alternatively you could also buy one of our Heirloom survival seed vaults which contains hundreds of great seeds with 20+ vegetables. Grow them continuously and then jar or pickle them when the time comes to harvest. Pickled foods that are well-sealed and kept at temperatures below 75 degrees can last up to three years. In addition to this, grow herbs for medicinal and taste purposes. Once you invest a couple of dollars here and there to growing food—even small amounts in your kitchen—it is truly a great return on investment requiring only a few dollars and some sweat equity.
Having been raised old school. I was taught bout to hunt,fish,live off the land. Bust best of all I am a 5th generation greenhouse grower. Get lots of seeds for a seed vault. Great to use and as barter. Learn how to cook over a fire in any weather.Guns are great but I have black powder, when you are out of bullets, I can make more with ease. Using a bow or snares will bring fresh meet. Teach these things to kids, one day they may save you. Just a few things from a country ridgerunnerme.
Tools may include cutting tools such as saws, axes and hatchets; mechanical advantage aids such as a pry bar or wrecking bar, ropes, pulleys, or a 'come-a-long" hand-operated winch; construction tools such as pliers, chisels, a hammer, screwdrivers, a hand-operated twist drill, vise grip pliers, glue, nails, nuts, bolts, and screws; mechanical repair tools such as an arc welder, an oxy-acetylene torch, a propane torch with a spark lighter, a solder iron and flux, wrench set, a nut driver, a tap and die set, a socket set, and a fire extinguisher. As well, some survivalists bring barterable items such as fishing line, liquid soap, insect repellent, light bulbs, can openers, extra fuels, motor oil, and ammunition.
