I have a question: We recently found out our son is allergic to dairy and eggs. He gets diarrhea & belly aches if he has the slightest bit along with a light rash on his back. My question is what kind of foods are good to feed him? How can I substitute things like yogurt in our smoothies or eggs in our pancakes to make him more comfortable? He doesn't drink cows milk only almond milk, but there is also 3 other of us to feed and I don't want to break the bank. Any suggestions appreciated.
