Dear Victoria,
Good for your daughter! Bovine dairy really is not healthy for the human body, and can contribute to all kinds of issues throughout life.
I began seeing a wonderful Integrative M.D. about a year and a half ago. She treats her patients primarily with diet, supplements, and exercise before turning to chemical medication (in most cases). The first thing she does is recommend avoiding all dairy (except yogurt with active cultures) and all grains (except oats). I use Trader Joe's Light Coconut Milk in place of dairy on my oatmeal or granola, and it is delicious.
And please don't add sugary flavors to your daughter's food! It's the worst thing we can do for them. Diabetes is at an all time high in this country, and we need to stop eating so much sugar! I use honey or pure maple syrup in place of sugar. Both taste excellent and they're much better than refined sugars.
If your daughter is eating a balanced diet, she will get enough calcium from other sources, like leafy greens, nuts, etc.
My grandson is allergic to dairy, and he hasn't eaten it since he was diagnosed with his allergy at about 3 months of age. He gets along fine without it, and is the healthiest child I've ever seen. He's rarely had so much as a cold, and he's 6 1/2 now.
If your daughter is not interested in dairy, please do not sneak it into her food. You could be doing her a big disservice. If you're interested in the "Diet for Life" plan that my doctor recommends, I can send you an outline of it.
