I have a 3yo daughter I suspect she has food allergies, I have been able to relate her bad behavior to the consumption of dairy products. It is vey difficult to keep all dairy products away from her an maintain a balanced diet, while cooking for the family. however just any dairy product leads p to a total melt down, kicking , crying, disobeying, ending with "I want to be a good girl, Mommy. I am a sad, sad baby" direct quote. Am I crazy, my pediatrician does not see the connection, or even the problem!!
