I actually think we may have tried lactaid as well, with a similar reaction. My wife would remember for sure.

There seems to be some disagreements among the healthcare community as well. With my son, we tried normal milk, goat's milk, and raw. The raw was the only one that didn't cause the gut issues. We mentioned this to his pediatrician, and he told us there was no difference. When we mentioned the variance to a different physician, he said there absolutely would be reason for him to react with the pasteurized but not the raw. I think he mentioned something about the breakdown of protiens when milk is pasteurized, but I can't remember for sure.

Oh, interesting. I'll have to look into where to find that.

So, I don't really understand the science, but my son is only able to drink raw milk. When he drinks normal milk, he has terrible stomach aches and mad diarrhea. When he drinks raw milk, it's all rainbows and butterflies. For reference, he's 3 and has been drinking the raw milk for around a year and a half. Also, the rest of the family had no issues drinking pasteurized milk. Maybe somebody smarter than me could explain why this is?
