When making a kit, the one thing to remember is "The first 72 are on you". This means food, water,shelter, medications and anything else you and your family may need. Don't expect anything from local, state or federal government during that time maybe longer. Be sure to take into consideration each family member individually. If you have a baby or toddler you'll need whatever food, diapers and supplies specific to them. Same goes for elderly or other special needs populations. These are the things people tend to forget. Have a first aid kit on hand, help may not be on the way. Prescription meds and otc meds. If there is someone who needs special medical care such as O2 or dialysis be sure to get them registered with the Health Department BEFORE a disaster, you can't just drop them off at a shelter.
