For example, have you considered the need for feminine products?  What about canes, walkers, and manually operated wheelchairs?  Pets need food, crates, and toys to keep them occupied while the rest of family members are recovering from chaos.  It will be impossible to cover every contingency but be aware of what those needs are now then prioritize those that you deem most important.
One of the first things to go in any disaster, or even just on a stormy night, is the power. Every standard family household has go-to flashlights and candles, as blackouts are an occurrence in every corner of the world (some areas more than others, of course). But for preppers, the answer to that problem is a generator. The only question is, will it be electricity or fuel-based?
It’s impossible to carry all the food you will need for a week unless you’re eating very high density proteins like nuts.  Nuts and dried meat are two of the easiest off-the-cuff meals.  Canned food has a lot of water that is wasted during the cooking process.  Stay away from heavily flavored or salted nuts.  The amount of salt present in the unsalted nut mixes is still sufficient enough to replace electrolytes.
