Most sizing charts rely on weight, but since no two babies are alike, the process can definitely be tricky. What to do? Look for diapers that are intentionally designed to overlap on weight, like the ones from Bambo Nature. We’ve been perfecting our diapers for over 30 years, using feedback from hundreds of parents. If your baby falls between two sizes, consider the smaller size if he’s long and lean, and the larger size if he’s short and stout. If you’re still unsure about sizing, give us a call at 844-223-6248—we’re here to help!
