The theory just seems extremely weird to me. First, Spike was hatched when Twilight was still young. As made clear in 'Amending Fences', Twilight was a pretty inattentive kid with her head lost in her books who seemed to be ignorant of most of the social relationships connected to her. Given this, I imagine Twilight wouldn't be a particularly good mother at that period in her life. If anyone was responsible for raising Spike, it would make more sense for either Celestia or Twilight's parents to be the ones to pick up the slack. Next is their interactions on the show. When I see the two of them onscreen (especially during the first 2 seasons), their interactions just seem to fit the mold of best friends/siblings rather than any sort of mother/child relationship. Twilight just doesn't come off as maternal to me in her interactions with Spike. She doesn't seem to imply anything maternal in any dialogue between the two and she doesn't seem to show him any additional affection on top of what she would show to any of her other close friends. The 'you're not mommy' moment (from S1 I believe) indicates that Spike likely doesn't see Twilight as his mother either. In their interactions, she comes across as the responsible older sister and him the witty, wisecracking younger brother. The mother/son headcanon is not an outlandish one to have, I just don't see it. This is just my opinion of course and I fully respect those who don't share it. I apologize in advance for the wall of text.
