Diaper Bags for twins

One bag, bought big. Twin parents do not need a special twin diaper bag, they need volume, compartments that survive being packed at 6am by a tired person, and backpack straps because your hands stopped being available the day the babies arrived. The twin-branded versions mostly charge extra for a word on the label.

The twin-specific test is capacity math: two of everything for a normal outing, and the bag still closes. Look for a wipeable lining and a changing pad included. This is a fine used buy (it is a bag), and a fine place to save money you will spend on car seats instead.
