Query: Hurts Back

I've tried this carrier and it really gave me a bachache after wearing it for a short time. Also the baby grows out of it very quickly. I love the ergo baby carrier (highest rated by users as testified on the baby bargins website) and am still using it with my 14 month old son. It can be used as both a front and back carrier and has a hip belt which is key! ergobabycarrier.com-Pam
