Interesting, given that Tatiana was supposed to be the daughter closest to their mother.

Yes interesting. Perhaps it's explained by the strong sense of camaraderie Alix & Tatiana shared. Being her mother's daughter (a kindred spirit in many ways) might have inclined Tatiana not speak about her mother's illness? Maybe this is a question for Helen, but did you notice a difference in how she speaks about her mother in letters as opposed to diary entries? Nothing stands out to me, but if she rarely to never mentions her mother's health in letters to others than I think it's obvious Tatiana wants to keep such things private.
Clearly Olga loved her mother, but they didn't always see eye to eye. Being more open about her mother's poor health - both in her private diary entries and in what she wrote to others - strikes me as a daughter who bemoans her mother's invalidity. Even exasperated by it at times. Tatiana on the other hand was probably more cautious. Revealing (or even thinking about) unfortunate things having to do with Mama was like revealing things about her own self.
