Follow-up
So, I went off milk for five days, and Lego only seemed to get worse. I racked my brain for what I was eating more of during those five days, and I realized that because of my birthday, I had eaten much more chocolate during those days than I usually do.
Even though it hadn’t been a week yet, I went back on milk and off chocolate. Each day that followed was better than the last. Lego essentially stopped spitting up altogether. He still does once in a while, but it’s not anything like what he had been doing. A week after going off chocolate, the diarrhea stopped too.
The clincher was on Monday. Sunday night I had a s’more and a chocolate-covered caramel cookie, the first chocolate I’d eaten in ten days. Monday, Lego was spitting up a lot and very fussy. Today, he has diarrhea again.
I had hoped that if it was chocolate, I would be able to eat very small amounts without making him sick. Looks like I won’t be that lucky.
Hm. I wonder what carob brownies taste like.
