Does anyone else get stupid comments from people?

I carry DS in the Sleepy Wrap. Or DD in the RS (back carry). DS (6w) isn't a big fan of the RS yet, he prefers the wrap and so do I at the moment..

I've given in to public demand and bought a $75 double stroller. It's fine, but I still plan to wear DS for a long time.

"You can't carry him forever!"
"That's cute, but it's not practical"
"Don't your shoulders get sore?"
"It doesn't look very comfortable
"Aww 'DD', you look scared back there!" (when she was actually cuddled against my back, quite happy.

Only one person compliments me on wearing DS. She had never seen someone babywearing before (Small country town) and was blown away by how natural it looks. She says that more people should do it, it's how babies were designed, to be close to mum. She's got an older child, so I never expected comments like that.

I get sick of people slagging off baby wearing. I really enjoy it, but feel like I have to defend myself everyday.
