I asked the Ped and she said 500 milligrams, so I was thinking I could dose down the adult calcium I found, but I wanted to double check first because there's another ingredient in it - can't remember at the mo what though.
I know about the liquid multivitamins not having the calcium

Who would have thought it?
I'm back to the Ped with him at the end of the month, so we'll discuss our options then. She also wants to send us to a dietician and for allergy testing b/c she thinks the aversion to milk *could* be his body's way of telling us that he's allergic.
