Create one for each family member on your smartphone so you can easily add or subtract based on variables like trip length and climate. Start with musts such as medications, extra eyeglasses or contacts, chargers and cords. Then list toiletries, basic clothing, underwear and something to sleep in. Also include a first-aid kit (ibuprofen, antacid, antihistamine, bandages, tweezers) and a charged external battery in case your phone is about to die and there’s no outlet (gasp!) nearby.
