hi ursula
i struggled to find a carrier that i felt comfortable with & ended up with an infantino sling - it is awesome & i hardly feel like im carrying bubba around - its also ergonomic? for you back & bubba loves snuggly into it plus i find my back always gets hot & this has just the strap like you have a bag diagonally on one shoulder - go to a baby shop & see what they will let you try on
