But considering the character goes "My baby! My baby!" at anything remotely related to the main quest line, it is pretty hard to justify ignoring it.
So i found most comfortable to play the game with the character i envision as a psychopath, and the "My baby! My baby!" part a well rehearsed act to gain sympathy and favors from the clueless wastelanders
A big part of the reason why i don't even have F4 installed, by the way. You should remember your level of writing, and not attempt the clearly impossible, BGS.
