There were so many days during our journey with Ellie's allergies and health that I shed tears over the worry that we'd never be able to have another child. I felt that she needed so much from us that there was no room to nurture another child (many days there wasn't even enough room to nurture the parents!). I worried about conceiving a child who would share her perplexing health issues and that that would simply be too much. And I worried about having a child who had even more severe issues than her, or different issues, and the idea of navigating a different realm of this brave new world of expanding chronic childhood disorders would be impossible. And, like any mother, I wondered how I could possibly love another little person as much as I loved Ellie.
