How to get your mom to stop blogging about your life
Go onto her blog website and write about her.
She will be annoyed and stop when she feels her private life has been exploited.
Consider why it bothers you that your mom is using you as " blog-spiration ".
If your mom is recounting your life in full technicolor, along with your name, this could be awkward and potentially embarrassing. On the other hand, if your mom is being fairly discreet and isn't calling you out by name, it might not be quite such an issue.
