I was going to say that this (although very good) wasn't quite Weird enough for your purposes; the principal value of the Baby-Eaters seems to be "individual sacrifice on behalf of the group", which we're all too familiar with. I can grok their situation well enough to empathize quickly with the Baby-Eaters. I'd have hoped for something even more foreign at first sight.

Then I checked out the story title again.

Eagerly awaiting the next installments!
