Don't know a lot about it but rang bells with the high calcium and developmental delay. People with Williams Syndrome are ratherly rudely described as having ' a cocktail-party manner' but I am not sure how that demonstrates itself in chidlhood . As you say she is young. There are other associated abnormalities so a whole body exam and a number of tests plus genetic testing would be needed. High calcium levels do not have very many genetic or congenital causes. I would think Williams syndrome would be high ont he differential list.
