My one year old son has diarrhea and undigested food in his stool when given cows milk. We switched him to soy, and he was perfect on it. Food digested and no more diarrhea. But now I am hearing all these things about the isoflavones in soy causing problems in development, and its freaking me out! Should I give goats milk a try instead? We also have oat milk and I was considering that as well. Obviously I would love to run this by his doctor, but it'll be another two weeks until I get a call from him. Here's a pic of my beautiful boy for attention.
