HAB is awesome for comfort and support for a newborn, my neice happily slept in it on me for an hour and I felt fine. Takes a bit of practice to tie up but ok once you get the hang of it. My DS hates being in a carrier and wanted to get out of it all the time so it didn't work for us. Much more supportive than other carriers I have tried cos it ties around the hips too, which takes a lot of pressure off the back and shoulders.
