Wow. I stumbled upon this website this morning. It's called Go Dairy Free.
It has a really thorough section with the research and information on food allergies. It has some recipes. It's a really great resource sight. I started reading up on milk allergy information. WOW. Some of this I have been wondering, some I knew and some described my flipping kids to a T.
Take a look... it's good information to know.
