Baby porridge = allergy

I noticed Kieran doesnt like to eat hard boiled egg so I made porridge in a different style today- with eggs, meat and tomatoes. But my baby developed patches of rashes on his left cheek and around his left eye after his meal.. sob!

Daddy and I brought him to see a PD near our home. When we reached the clinic, the rashes have subsided. Doc said it may be due to eggs, even though he didnt develop rashes the last time. My friends told me may be due to tomato because it is one of the food that causes allergy (???). Looks like I have to test again when Kieran recovers.
