Oh, God. I had one of those types accuse me of putting my baby in a cage because we had her sleeping in a crib.

There are serious class issues to tease out in the way that middle/upper-middle-class families have adopted practices born largely out of necessity and poverty and glorified them as "natural" while looking down on women who have fewer options* (women in poorer areas generally don't wear their babies for bonding and nurturing; they wear them because they have shit to get done and don't have playpens, much less daycare). I'm sure someone has already written about it.

*Note: I'm not talking about all AP parents, just the extreme ones who get self-righteous about it.
