Ergo carriers should be issued when a child is born. I carried my first child in an original Ergo 7 years ago very successfully until he was 3, or maybe even 4, on occassions. This sport version was an essential for my second child as my husband is 6 foot 7 and so very limited by the carriers that he can use. We are both able to use this carrier, with comfort and ease. Worth every penny.
