What you really need is a fabulous Mei Tai baby carrier from BabyHawk. The company calls their design "the cure for the common baby carrier" and there couldn't be a more apt description.
Several weeks ago I dragged myself into Metrominis wearing the Kiddo in our Baby Bjorn, my neck, shoulders and back aching with the familiar strain. Bianca, the owner of the boutique, staged an intervention, informing me that the discomfort I was experiencing was not due to the weight of my baby or any inherent problems of babywearing, but rather to the less than ergonomic engineering of the Bjorn. Then she introduced me to the BabyHawk, letting me try it on in the store. Well, I've barely taken it off since! The BabyHawk is comfy and cozy and cute. It gets the baby nestled right in, close to your skin and promotes majorly soothing vibes. Due to the way(s) that it ties onto my body, the weight is well distributed -- so much so that I can wear it for hours at a time without any signs of the tortuous strains that were common when wearing the Bjorn. Bianca also pointed out that the BabyHawk is better for the little one's hips, as well (because it positions the baby's legs like a "froggy" around your waist instead of letting them dangle straight down).
Another reason to love BabyHawk carriers is that they come in a plethora of beautiful, designer fabrics (you can even design your own on their website). As you can see above, I selected a wonderfully whimsical and slightly punk rock print featuring mini calaveras. Because what could be better than festive, glittering, Mexican Skulls on your baby carrier!?!
I'm also digging this one:
