14 month ds just ate a pea sized amount of hummus for the first time. He has had allergic colitis in the past and has a dairy free gluten free diet. Immediately after eating hummus his eyelids have swollen and his face blotchy. He has just fallen asleep but should i call the doctor? He was scratching his eyes a lot before he fell asleep. Could his symptoms get worse? Bit worried, any advice appreciated.
