This time it's the Baby Trend Back Pack Carrier. The company has received 17 reports (with one report involving a small injury) of the shoulder straps coming loose. The stitching on the strap seems to be the issue in this case.

You should stop using the carrier and contact Baby Trend at 800-328-7363 for information about how to return it and get a free replacement. There was nothing available on the company's Web site at the time of this writing.
