I just wanted to share that I managed to fix the issue where the game would crash after picking up the knife near the beginning of the game. Still not entirely sure how I fixed it, but I had to rename some game files and then change them back. Modding can be quite strange, haha!
Also, I added new diaper textures to the mod. If you want me to make any textures look dirty as the game progresses to simulate her using them, let me know.
