my 14 month old ds us allergic to dairy and gluten, which has manifested in allergic colitis. Today he had for the first time a pea sized amount of hummus on his toast. His eye lids have swollen immediately and he cant stop scratching his eyes. His face is a bit blotchy. He has just fallen asleep and stopped scratching but should i be worried? Could there be any more severe symptoms? Should i call the doc? Sorry, be worried, not sure what to do.
