I have a HAB and used to use it all the time but not so much anymore, probably because DD is happy in the pram now. I have not seen anyone else wearing the HAB around here but have seen a few in the baby bjorn, again not that common though. Our local shopping centre is a swarm of prams! We always got stared at when we wore the HAB (especially my DH) but it wasn't a bad stare, it was more of curiosity I think. Another friend has a different kind of sling and she used to wear her DS everywhere (she doesn't drive so walks alot) and she finds it fantastic (and so did he). If people stare it's probably just because they are curious. If i didn't have the HAB when DD was little, life would have been a nightmare! Good luck.
