My 20 month old son was diagnosed with ITP a few weeks ago. He had IVIG treatment and we were told this is a common disease and would resolve on its own. Here we are back in the hospital for another IVIG and dangerously low platelets. We are so confused and it's difficult to understand what went wrong. This certainly doesn't seem common to me as I have never heard of this before. Does anyone share this experience? Any advice on how to navigate the peds hem/onc world?
