Chico is 8 months now and I know for a fact that egg yolks is safe for babies that age. Yesterday I have him eat some egg yolks. Later that day, his face developed some rashes. Rashes started on his face, then to his tummy and spread into his arms and legs. Alarmed, we called his pediatrician and ask what is a good antihistamine for his age. The pediatrician prescription was to treat it with Zyrtec (Cetirizine dihydrochloride), 5 drops,once a day for 5 days. It seems he had developed egg yolk intolerance or egg yolk allergy (which is rare, so I hope not). According to a baby food site, that egg allergy appears when the body mistakes egg protein as a harmful substance, thus the body releases antibodies. Chico’s immune system is up and still fighting off egg proteins as he still have some rashes now. He is so red right now, good thing the redness on his stomach is gone and only some patches on his face is present. No more eggs for Chico for now..
