Traveling with children requires creativity in packing, says professional organizer Sylvia Daoust. It’s a challenge to have what you need when you need it and still economize on space, so make a packing list for your summer vacation ahead of time to avoid leaving something necessary behind or taking too much. Equipped with a list, children as young as six can pack their own suitcases, but you’ll want to have snacks, music, toys and “screens” on hand to keep them entertained — and especially if you’re traveling by car.
