IK -
Definitely understand the not being able to win no matter what you do in public. I wore DS in a sling, then Baby Bjorn, then HAB for the first 6-8 months of his life and the comments I got from some were ridiculous. I would still wear him except that I'm pretty short and he is pretty heavy and the HAB sags after he has been in it for about 15 minutes and then it gets uncomfortable for both of us. I have been looking at and lusting after the Ergo as I think DS would like riding on my back, but I just can't justify buying ANOTHER carrier - I think DH would have an absolute fit!!
