Hi Julie-Glad to hear from you. :) What do you mean by being on corticosteroids that their bodies would absorb only so much? I didn't know that. See, I constantly learn something every day on this MB. I give him a vitamin that has 200mg of calcium and he drinks about 2-3 cups of milk a day. I wonder if I should be giving him more. I looked up the Magic website to see if I could find what you were talking about, but it didn't say anthing about any studies. I just got off the phone with Cathy Kusch (director of the CAH division) about an hour ago, I should have asked her. Honestly, if my head weren't attached, I'd forget that all the time too! :) I think I will ask Dr. Pang that in the next newsletter. Julie, are you a member of Magic? Anybody else out there? Has anyone been to the conference in Chicago? If so, how was it? I am thinking of going next July.
