We have been going to the allergist every 6 months since this little boy was born. At age 2, his blood test came back negative for his milk allergy. But his skin test was still positive. At age 3, his skin test has come back negative! What's next? A food test. He came into the allergist and drank milk to see if/how he reacted. He did great and got the all clear! Cheese and ice creeam, here we come!
