Did a bit of research. 30 kg is noticeably underweight for 130 cm, yet 130 cm is also in the average range for height of a ten-year old girl. Nikaz does not look malnourished, and if she was, she would probably be shorter due to stunted growth. She doesn't look particularly skinny, either; just a bit slim. I was looking into it because I wanted to suggest having wellness affect the speed and result of Nikaz's growth. I'd use a bell curve for determining how much each point of wellness is worth (basically, you choose a value that is has the biggest effect and have diminishing gains the further you are from it), as well as having a hard cap where extra points stop having an effect (maybe around 300?)
Also, I know the guidebook says that it is impossible to ever get over terrors, but perhaps have killing them reduce the mood penalty from them. After all, the knowledge that they can no longer hurt anyone should at least give some level of relief. I admit this was taken from Eternal Darkness, where performing a finisher on an enemy restores part of your sanity meter.
