belfie- i have to tie my dp into the hab as well, but once he has it on, he's fine.
my dp is 6'1 and he really likes wearing the ergo. he finds it very comfortable.
if you can find a cheap hab -maybe from ebay- or make your own until your baby is 6 months, and then purchase an ergo- i think that would be the best way to do it.
for my next baby i plan to do exactly that- use my hab until 6 months or so, then use the ergo.
