His wife was not a vampire, and the child she carried was part a creature that fed on blood. The doctor had mentioned that she was weak and wasn't eating properly, but the right words were—she wasn't taking blood that the child needed.
This was part of the reasons why he had been so worried learning about her pregnancy now. They were in a land where they could not just get access to blood supplies or hunt down humans too often. Compelling a human was easy to take their blood, and as safe as it might be, it wasn't entirely safe, as their bite leaves a mark on the human, and if another human were to see the mark, they would realize it was done by a vampire.
She needed a constant supply of blood in this condition, and the more the child grew inside her, the more blood it would need.
If they were in Nightbrook, he knew he wouldn't have to worry about getting blood from any random human, as no law could hold it against him. It was different here.
