After five years of using the Ergo baby carrier, we have no complaints. Hundreds of our parents have also purchased this baby carrier and are extremely happy. It is design for babies 5 months and up. You can purchase an insert an use it for you infant as well. It provides great back support and you will be surprised at how well it distributes the weight. Unlike other carriers, the baby is sitting in a squating position which is a lot better for them (instead of having their legs dangle). Organic fabric is softer and kinder on your baby and the environment.
