There are instances that Edmond is aware of that Mrs. Norris is not interested or concerned for Fanny's welfare.

First there is the horse incident. After Fanny's horse died, Mrs. Norris had Fanny walking about to ill effect which Edmond noticed and declared that Fanny must have a horse. Mrs. Norris offers a few ineffectual suggestions such as any old horse that's about would do for Fanny or borrow Dr. Grant's pony now and again as she feels Fanny is undeserving of a horse of her own. When Edmond decides to provide one from his number, Mrs. Norris is only tolerant of this idea because Edmond keeps the horse in his name instead of giving it to Fanny outright.

There is the incident of Mrs. Norris making Fanny take two round trips to her house in the heat causing Fanny a migraine. She is showing a total lack of concern for Fanny's health and interested in her own selfish ends.

When Edmond arranges for Fanny to go to Southerton, Mrs. Norris tries to keep Fanny from going and is quite testy when she doesn't get her way.
