I'm looking to get a sturdy carrier that won't hurt my back or shoulders, something that we can use for hikes long walks, shopping, sightseeing, etc. My DD is 8 months old and about 17 lb and I *think* she'd like the front facing position w/ her legs dangling. I'm about 5'7" and a size 22, and DH is 5'10" and a size XXL, so it needs to fit both of us. Something that could be tucked into the diaper bag would be nice, but not a necessity. I have a KK cotton pouch, but it has hurt my shoulders since DD was about 3 months, and I've been carrying her in my arms ever since. I'm intrigued by the Baby Trekker, but don't know anything about it.
