Query: Hurts My Back

I first got the Baby Bjorn 2 years ago when my son was born. The only problem I have with this carrier is the pain I get in my back and shoulders. I used thisfor a little while, but it really hurts my back. I decided to give it another try with my daughter who weighs 11 pounds. My back still hurts. One of the other reviews suggested moving the criss cross straps lower. Both of my babies like the carrier. It works well for when I want to calm my daughter, she will usually fall asleep It's great for the babies. I'm still looking for a better carrier and will also try to figure out how I can use this without being in pain.
