What We Store and How We Prep: 72 Hour Kits

(Our 72 hour kit is growing...I think we need a second tote!!)

I have posted about this subject recently, but one of the ways in which we are attempting to become more "prepared" is by creating a 72 hour kit. My husband has been wanting to work on this project for a while as a family, and I kept stalling because I thought it would be too time-consuming, too expensive, unnecessary, yadda yadda. I made up a lot of excuses.
But, thanks to a few minor emergencies, and the realization that I have more to care about than simply myself, I managed to get inspired after doing some searches on Pinterest, and found a post that encouraged me to get started. I modified the list a bit, since we have an infant in the house, as well as a dog, and I tweaked some amounts to work for our own family, but the premise is still very much the same.
Our kit isn't complete, not by a long shot, but we're getting there. I still need to pack food for the baby and the dog. We need to add in some lists of important information, phone numbers, etc, as well as adding in some money and change. I need a few more various supplies, like a spare leash for the dog, a copy of his rabies certificate (in the event a shelter requires one), matches, bug spray...you get the idea. There are some small gaps to fill.
But the thing that intrigued me the most is how much of the stuff we already had on hand, since we believe in buying in bulk and stockpiling. And I think that preparing our 72 hour kit has inspired me to stockpile even more. Last night, I managed to snag 8 hand soaps and 10 boxes of bandaids to stockpile, and we went to Sam's Club to get things like regular soap and toothbrushes. The hubby wants to get some MREs to put in so we can have meals that are more filling. I think that, with any kit, there are always things you can keep adding. We have added a lot since my last post on this concept. And there's still plenty more that can be done.
We also have an unfulfilled goal to create a kit for each car. We have a semblance of one in one of our cars, but it's a bit pitiful. Our idea list is:

In addition to two car roadside emergency kits with jumper cables and such—

-a small first aid kit for each car

-spare shoes for me

-a blanket or space blankets

-clothing for kids (pj’s) and pants for me

-diapers/wipes/underwear for Goob

-a couple portable baby food containers, granola bars, and a baby spoon

-four bottles of water per car

-flashlight per car

-very basic tool kit

-duffel as containers

We contemplated getting premade 72 hour kits for both the home and the car, but at the end of the day, we actually felt it was cheaper to raid our stockpile first and make our own, than to add to an already created kit. The kits for the cars are our next priority, and we need to get started on them.

What do you have in your 72 hour kits, if you have them?
