Damn Soy Milk.

So once upon a time Lincoln was on rice milk and doing amazing. Then I gave him soy milk. He didn't seem to do well on it and cried at night a bit. Back to rice milk. Did great slept amazing. It's been about 4 weeks and we ran out of Rice milk and he has has soy almost all day about 4 times today. He keeps tossing turning and crying out in his sleep. He wants nothing to do with me. Just keeps screaming "Owww" and "NOOOO!" I HATE when he is uncomfortable. I had a feeling it was the soy last time and he is doing exactly the same thing after drinking straight soy. It doesn't seem to bother him in small amounts in food. hmmmm hate this. :(
