If you have a baby, you’ll want to have a reliable diaper. A diaper leak or blowout can ruin a day out or a much-needed stretch of sleep, as well as leave stains on clothes, bedding, car seats, furniture, and anywhere else a little one is placed.There’s no one diaper that will work perfectly for every baby. But after testing 14 models in a laboratory and then testing 10 of them at home, we’re confident that the house brands from major retailers — Target’s Up & Up Disposable Diapers, Amazon’s Mama Bear Gentle Touch, and Walmart’s Parent’s Choice Dry & Gentle Diapers — are the best ones for families to start with. They typically perform as well as much more expensive diapers, and you could save thousands of dollars over the course of a child’s diaper-wearing years.
