I tried out the Tibetan back carry and went for a walk with my son... (22#, 9 months) I really liked how it felt at first and he seemed *very* secure. My problem was that my lungs felt seriously compressed. The chest belt is awesome because it helps pull the carry together and seems to help take the load off my shoulders. Has anyone else had this problem and does anyone have any suggestions to make this carry work better for me? I really like it other than the my lungs being compressed!!!
