Hey Bonnie, You are no more of a pain than I am! I'm sure that these people are tired of seeing my name on this message board... "Oh no, not her again!" It has been a tremendous help to me, though. Connor had his first bone done at 13 months to have as a baseline. They said they would repeat it if he started lagging in growth. We can only pass down the disease if both parents have the trait. Each child has a 25% chance of disease, 50% chance of carrying the trait like us, and a 25% chance of being "normal". If one parent has the trait and one doesn't, the child could only inherit the trait, not the disease. Mind-boggling isn't it. Hope all goes well with your appt. Andrea(Andy)
