I would recommend focusing on things that get you more equipped to “bug-in” and your bags for leaving the house contain what you need to get by at a friend’s house or hotel. Our bug-out-bags are pretty simple and light since we’ll also be moving around with a toddler. He came into the world about the same time as COVID so we’ve navigated a lot of supply chain issues. we just but things in bulk and follow FIFO. We typically bought a couple big boxes of his current diaper size and the next size. It wasn’t too big a deal to eat the cost of a box of diapers if he grew out of them while we still had some. The local diaper bank was happy to take them. We have a change of clothes stashed everywhere, often a size or two too big to minimize having to swap them out frequently. It doesn’t get very cold here so over-sized t-shirts go a long way in a pinch. A battery-powered sound-maker is pretty good when the power is out. You can also get phone apps that would work too but I haven’t looked into it. I hope that helps. I’m typing while being told it’s ‘his turn’ to use the laptop. I think it’s great that you are working to make you and your family more resilient. In a way it simplifies things — anything that involves tents and camping isn’t practical for us. Luckily kids are pretty resilient.
