If she's allergic to milk, you're not doing her any favors by loading her diet with dairy. Milk allergies are different from lactose intolerance - lactose-free or low-lactose dairy foods are not appropriate for a milk allergy (to milk protein).
There is excellent, well-researched information here calcium for dairy-free diets: http://www.godairyfree.org/Table/Health-Info/Calcium/ and the whole site has a ton of information on non-dairy foods. I avoid both gluten and all dairy, so I use it often.
Here are some more suggestions to increase her calcium sources: Give her yogurt, yogurt smoothies (yogurt, fruit, and ice cream blended), all types of cheeses, ice cream, puddings, put cheese on vegetables or make them with heavy cream sauce. Mix yogurt into fruit and have snack cheese sticks. Make pasta and cheese or add cheese to rice and beans. Some children will accept whole milk if you add chocolate or strawberry flavor mix to it. If that does not work and she likes soy milk, then give her soy milk (has the same amount of calcium as in regular milk). Hoped this helped you.
