How to get my 2 year old to drink milk?

Since he was weaned from a bottle at nap and bedtime, my toddler refuses to drink milk. Period. And he used to loooove the bottle. Here is what I've tried so far...putting milk in a sippy cup, a regular "big boy" cup, telling him all his favorite people drink milk (daddy, cousin, Woddy from Toy Story, etc), buying a special cup with a crazy straw, getting a transitional sippy cup with a soft spout, and only giving him the option of drinking milk at mealtimes. He wants absolutely nothing to do with them and I've been completely unsuccessful so far. I'm just concerned he isn't getting enough calcium. He is the typical picky toddler, he'll love yogurt and cheese one week, but hate it the next, so I can't always rely on that for his calcium intake. He also doesn't drink juice, never has, just water. I'm not opposed to juice, he just won't take it. So, calcium enriched orange juice is also out. Anyone have any tips?
