Hands down the best carrier on the market; I have used Tula carriers with both of my kids; they are responsibly designed and made from 100% breathable cotton, and they have multiple adjustment capabilities to find your perfect fit as the baby grows. Can be used from 7 - 45 pounds. The Free-To-Grow carrier focuses on fit - cradling small babies as they grow into toddlers. And for adults, the carrier adjusts multiple wearers' shapes and sizes, giving an ergonomic fit without the bulk. Simple comfort.
