I would also recommend the ergo baby carrier because it can be used in the front, the back, the side and up to about 5 years old! I love mine for my 4-month-old. We started out using the infant insert and now he is big enough to use it without anything. He love being close to me and it is comfortable for me and my husband. It is also created so that the baby's hips are supported, unlike the Baby Bjorn. They basically are in a sitting position instead of just hanging there. Also it is designed by a mom from Hawaii, which is also where they are made. They are made out of cotton (organic available too) and there are also attachments that you can buy. I love the backpack. It's the perfect size for a diaper bag and it attaches to the carrier so you truly can be hands free.
