Dr. Susan Niebur was a planetary scientist with her feet firmly on the ground. Writing as 'Whymommy' on her blog Toddler Planet, she inspired many with descriptions of her battle with Inflammatory Breast Cancer and her commitment to be, as long as she could, a mom, a wife, and a friend.

Unfortunately, Susan succumbed to breast cancer on February 6, 2012.

Now it's time for those of us who followed her blog or read about her here on Care2 and in dozens of articles and TV and radio stories to send out thanks and love to those she leaves behind.

Sign this message and leave a note about her impact in the comments. We'll be sure they go to her husband Curt and their sons.

Let's honor her memory by pushing our fight against breast cancer every day!
