Bloody child

When I read books or short stories I'm always curious as to where the name comes into play. Like in Neuromancer it's the AI or in Snow Crash it's the computer virus. It's always weirdly gratifying to see the author drop in the name and you're like "woaaah I get it now ha", but for this short story, I didn't get that. I was left wondering who, or what, is the blood child. I think back to the part in the story where T'Gatoi is operating and Lomas and she pulls out the worms that are literally latched onto his insides and Gan comments on how bloody and red they are and how he can't tell what color they actually are because of how much blood they're covered in.  Later, when Gan is contemplating murder or suicide, he asks T'Gatoi what Terran blood tastes like because she fed on the veins of his father. Maybe blood child are the Tlic that are born from the blood of humans. 

During the part where T'Gatoi is performing the surgery on Lomas, Gan sees that she feels no emotions as she has to dig around Lomas' internal organs to find more worms. I think this reveals a lot about her character and what she actually feels for humans. She doesn't care that Lomas might die or is in pain just as long as the babies survive, and Gan realizes this as well. This disturbs him because how can someone not feel remorse or fear when they see one of their own being put through such intense pain? I think Gan pictures himself in this position and that T'Gatoi will react the same way. Perhaps he sees that maybe T'Gatoi doesn't actually care about him like he previously believed. This is what I got from this interaction at least.

I also just had a few questions about the Tlics and N'Tlics. How does one reach the stage where Lomas was in? Why did these babies need to be put into an animal so quickly before they were born when other Tlics could be born from humans? These are just semantics but things I was confused about as I read the story.
