18-month-old baby who often has a rash around the mouth after eating tomatoes or dishes with tomato sauce.

Hello,

Tomatoes are basically acidic foods and can be irritating. I don't think we are dealing with a food allergy here

Especially if the symptoms disappear after 1 hour, it seems to me more an irritation of the mucous membrane, than an allergy.

Yes, of course!

I understand,

If it was an allergy, there would probably be 2 main characteristics. With each exposure, i.e. each time your baby eats it, the level of the reaction would increase. Also, there could be tingling or burning in the throat. He or she may have abdominal pain as well.

At this point, I really think we can rule out allergy (as long as we don't see the symptoms I just mentioned).

I hope that answers your question

You did well to send me the picture. It's more extensive than I thought. If it's worse than the other times, it's a sign that the reaction is progressing. For now, I think you would be better off not giving him any more tomato products. You don't necessarily have to conclude that he is allergic right away

However, it would be better to wait a few months and expose your baby to tomato products again afterwards to see if he or she still reacts. A break followed by a new exposure to the allergen usually confirms the allergy

In the meantime, if the redness does not disappear after an hour or two, you could apply a small cream based on ydrocortisone 0.5% (low dosage and safe even for newborns) twice a day. If everything is gone after a few hours, there is nothing more to do

It's a pleasure, if you have any other questions, I'll be happy to answer them
