Someone from another list I am gave me this idea. They grind up calcium tablets (calcium gluconate worked well for me because they are quite chalk like) and add them to their baking. I add them to my flour in the bread machine, to orange juice (we can't get calcium fortified OJ here in Canada), and when I bake I throw some in too. As the mother of a rapidly growing toddler, I was very excited to learn of such a great idea that does not involve endless meals with bok choy and other calcium rich veggies. Hope it helps someone else out. I guess the important thing to remember is to get vitamin D also, to work with the calcium. Cathy
