There are some weight considerations in that MREs weigh more than freeze dried food but they do have their advantages. I have a few boxes stored as part of my food storage plan because they are an easy way to get the calories you need for survival. I also have food stored in buckets, canned food and freeze-dried food. I am an equal opportunity food storage person and there is something to be said for having variety. Are MREs the the best prepper food? I don’t think there is ever a single best food for all prepper situations, but MREs are proven reliable. If our military uses them you can bet that you could find reasons to use them too. They are more expensive than other options but you don’t have to prepare anything, they even throw in the salt, pepper and a little moist towelette to wipe your face and hands when you are done. They used to come with toilet paper and chewing gum but apparently that is not part of these MREs.
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.
The next thing that you should be aware of is how to use the food that you have prepped and stored. Get familiar with stored-food preparation and the best way to do this is to use it. Get a couple of food-storage cookbooks, or create your own with a little online research. This way you and your family can become familiar with how to use and eat these types of foods.

This is a very basic guide to bunkers. Many areas such as bomb blast related pressure as it relates to entry door integrity really deserve much more coverage. And the section on construction techniques completely miss the point on culvert strength which is primarily related to earth arching and not the strength of the culvert material - look at the huge plastic highway culverts that are a few feet underground and support multi ton trucks. This book is a start but you need much more information to plan any kind of shelter.
Hello Ryan. My experience has been that the more that you can keep air (oxygen) away from your food the longer the shelf life. I like to seal packaged food into larger mylar bags with an oxygen packet, then I seal the bag. I store these mylar bags in a 5 gallon bucket with lid. Wal Mart has these buckets for sale that cost $2.97 and the lid is $1.12. I personally like having a few barriers between my food and mice, bugs…etc. Let us know what you decide to do!

Survivalists' concerns and preparations have changed over the years. During the 1970s, fears were economic collapse, hyperinflation, and famine. Preparations included food storage and survival retreats in the country which could be farmed. Some survivalists stockpiled precious metals and barterable goods (such as common-caliber ammunition) because they assumed that paper currency would become worthless. During the early 1980s, nuclear war became a common fear, and some survivalists constructed fallout shelters.
Grains. Grains are good for making flour or meal. Wheat and corn are the most common. Bear in mind that you will need a grain mill to process these, and I recommend a good hand mill in case power is an issue. By storing whole grains instead of flour or meal you drastically increase storage life. Again you can buy these in ore-sealed buckets, or repackage bulk purchases yourself to save money. If you want to increase the shelf life even more, you can turn them into flour and then into Hardtacks.
“If you’re using it for emergency survival, the fact is you’re going to buy it once, and hopefully you’re not going to use it,” Shields said. “But it’s there as a safety net for you and your family.” That’s what intrigued me about freeze-dried food: You can wait up to a quarter-century to use it, but in an ideal world, you wouldn’t have to eat it at all.
