Title: Fish reaction
Post by: Newbie mum on November 18, 2016, 22:13:48 pm
I wonder if you can shed some light for me... My 7 month old is enjoying solids and eating everything offered. He has a wide,varied diet and a week or so ago had fish pie (salmon, cod and haddock) and thoroughly enjoyed it. He had it on two different evenings with no reaction.
A week later he had it again and developed a localised rash on his face. Went away fairly quickly. We tried him again the next night and same thing happened.Any idea why after being ok the other two times?
It was a shop bought  fish pie made in-store by the fishmonger. Perhaps different fish was added this time? We'll wait a week or so and then I will try him just with poached salmon that I have prepared at home.
Shame as he really enjoyed it.

Reactions don't always occur on the first time. It can take multiple contacts to a food to develop an allergic response big enough to be seen.
The way the immune system works (very over simplified) is often the first time is ok because the body has only a few antibodies to it, but because it has some the next time those antibodies multiply & subsequent times they multiply, so simply put if there are 10 the first time & 2nd time those 10 multiply 10 times it becomes 100, which the 3rd time becomes 1000 at which point the body starts to show a response.

At 7mo I'd be more inclined to just offer 1 fish at a time rather than a mix so you can identify clearly what the issue is.

Try putting aquaphor or Vaseline around the mouth before eating fish. It is most likely a contact reaction not an allergy. Avoiding the fish completely may turn it into an allergy. My DD reacted the same way to salmon. Now we have no issues with it.

Thanks ladies. Yes, thankfully just limited to skin and only areas in immediate contact. He had a fish finger this eve with no reaction and will give some salmon soon.
