My 13 month old will not drink milk either. We tried everything. Watered down milk, flavored milk, soy milk, pedisure, skim milk, powdered milk, sippys with straws, about 3 different regular sippy cups. The only thing we didn't try was goats milk. It was like $3.00 for two cups. What I started doing was cooking with milk. I add whole milk to everything that I cook for him. Eggs, sugar-free pudding, mac and cheese, muffins, pancakes, waffles. I also add powdered milk to all of his baby food, yogurt, pudding, anything that I spoon feed him. He still eats like a champ. I also give him the oj with the calcium added. I look for foods and juices that have the most vitamins, calcuim and protein. His doc said to try a bottle (he is also breastfeed with no bottles), I just could not see doing that. So this is what I came up with. It is easy to track how much milk he is getting. Also, remember not every kid is going to drink milk and they will be fine. I weaned any way.
