Slightly off topic parenting discovery: if you're the dad in the USA, you can count on general approval or at least tolerance for just about anything you do with your kids in public so long as you're not hitting them or screaming at them. It's kind of insulting that the standards are so low, but most people still seem to expect dads to be clueless, and/or they treat taking the kids out in public by yourself as an extra credit activity for fathers.
Amen to that. I've gotten the "how nice, babysitting duty?" thing a lot, which I find really insulting. "No, this would be daddy duty" is my usual response. I tend to get it especially when I'm dual-babywearing (Ergo carrier in front, Cocopak carrier in back) at the grocery store.
