Yes we take calcium with vitamin D and K. My bones are fine so far and then some. But my question is do children have to have a bone density scan. My daughter has an appt this month I will have to make a note to ask her about that. Another thing they have never done is have her electrolytes looked at. I have however requested it be done by her ped. Seems to me they would do that on a regular basis too just to make sure those are in place.
