I didn't like it at all. I agree, sounded like publisher interference. I get that by having Katniss give in to children was kind of a hope for the future, and giving up of fear, thing. But I felt like it was another sign of weakness in Katniss, and deviated from the thing that Plutarch alluded to that life is cyclic, and people have a thing for destroying themselves - - basically that one day, there will be death and war again. I think Katniss would have seemed stronger in the end if she held on to her one conviction from the very start of the story, that she'd never have children. She had this conviction long before all her trauma.
