Welcome to the forum.
Some other questions may help us better assist you in your efforts...
Are you planning to bug in? (i.e. stay in your home?), or make a run to some other secure location? (will really impact your plan)
Do you or other members of the household work far from home? (to see if you need to consider how to get home if something happens while at work)
Are you in a major city or more rural? (different strategies for each)
Do you have a well, or city water? (water is the first important item, as you can't live without it for long)
How old are the kids? (infants, toddlers, kids, teens)? (so we know what challenges there)
7 kids, whew! Any pets to consider?
Some general advice....
For long term survival, these two are crucial.....
Renewable water source: Whether a well, rain water collection, or access to local freshwater sources
Renewable food source: A garden, raised chickens, raised rabbits, etc.
Home-canned food lasts a LONG time (5-10 years or more)
Dehydrate your own food, and make your own survival food
Store bought canned food typically lasts 1-3 years
Stored water should be treated/purified after 6 months
Dry pasta, rice, corn, beans, mashed potato flakes can last 15 years or more if stored properly
Try to stock up on things you actually eat, and can rotate through, constantly keeping your stockpile fresh. You don't want to have to add a major diet change to your challenges.
Learn at least the basics of hunting and fishing (or designate some of the kids for it).
If you don't currently use firearms or keep them in the house, make sure EVERYONE in the house is trained on them, and in gun safety. Keep the guns somewhere locked up, preferably with trigger locks too. Same with ammo. Gun safes are expensive. For a cheaper solution, add an exterior doorknob with lock to a closet instead. A range or friend with guns can usually help you find a gun that works for you, your size, and any other attributes. Ask 12 people what is the best gun, and you'll get at least 10 different answers.
Don't panic. Chances are you'll never have to go through a SHTF event, so live for today, but with just an eye out for tomorrow. Don't let fear grip you, or hold you back. Treat it as a hobby, and it will be one, vs. an obsession.
