DW is pretty much just not up to dealing with that sort of emotional fallout

IA. And it's not just that it's not up to it, it's that it shouldn't really have to deal with it in the first place. It's a family show that has a very large number of kids watching it, and while I applaud DW for some of the themes it's tackled in the past, and I certainly think that it's right for kids to be challenged to think about all sorts of stuff, I think that two of the main characters losing their baby was a challenge too far.
