Some are things that were holes in my preps, others are just things I'm learning through actual usage of what we have.
Holes:
Not enough masks and gloves. You can burn through nitrile gloves pretty fast on every day things if you're really trying to be careful. I've transitioned to some of my old patrol gloves that can be washed off after use for some things. Masks, we are improvising.
Kids books and activities. We have what we have, but without being able to introduce something new every so often, it would get pretty stale.
Fish food and supplies. I keep plenty of dog food but I didn't consider my boy's fish. Mainly because they are useless.
Flour. My stored flour somehow got bugs in it. I had to dump it all. Plenty of corn meal, no flour. For a week or two it was really hard to get more. We have some now, but I'll lay in more soon and figure out a better way to store it I guess.
Yeast. I didn't have any.
I need a bigger freezer.
I had two months of toilet paper going in to this. I thought that would be plenty to get through anything short term. That situation hasn't gotten any better, so I'm ordering TP from places that are shipping in about 3 weeks or so.
General use learning:
When everybody is home, meals become a bigger, more elaborate thing. Big family breakfast, lunch and dinner means we go through food stocks faster than I thought we would. We could easily pare it down but family meals are also a great social time right now so I don't want to. I just have to recalculate when I am figuring out how long my supplies last.
Sides. I did not plan on enough side dishes to go with meals. Like, we're fine if this were real survival eating, but making family meals there are certain expectations.
Alcohol. We are going through that faster than I ever thought possible, and we aren't even day drinking. It's just, when you spend all day with your whole family under one roof, when the kids go to bed, you really want to relax a little, refresh for the next day. I'm going to have to look in to making some kind of home brew or something. Or get a second house to store my booze in.
Planting. We got ready to start our tomatoes, realized we had no seed cups. Had to improvise. Such a simple thing to keep on hand but I hadn't thought of it.
