;) My son is almost two and still wants to drink milk at least 8 times a day. I realize to much dairy is not good, but he will not drink soy. Is there anything I can substitute for that tastes like milk? The other problem is he will only drink it from a bottle.

look into a gf/cf diet.
most people crave the foods they are allergic to.
I would elimate that from his diet, if he starts demanding cheese. Cut that too. after a few days you will notice a change in behavior negatively at first, then a great pick up in cognitive skills. After several weeks re-ad milk and see what happens.
another possibility is a canditis infection.
