Feeling confused after hives reaction to multiple foods

[madhen123]

Hello,
Bit of a long message but please hoping someone can help.
My baby is 7.5 months and we think she has a milk allergy. Every time we've tried giving her formula in the past (she's EBF) she's vomited. The first time she had formula, when she was 2 months old, i ended up taking her to A&E because she threw up all the formula and then wouldnt keep down breastmilk and kept throwing up her feeds. The doctors said perhaps we had given her too much formula, as we gave her a full feed instead of introducing it slowly, because she had only had breastmilk until that point she might be sensitive to the change. So we didnt think it was an allergic reaction. About 2 months ago we tried her on formula again and she threw up. But no other symptoms. I tried her on a different brand a few weeks later and she threw up, and where the sick touched her skin she came up in red blotches. Since then we tried her on another brand but this time we dripped some on her skin rather than making her sick, and she came up in localised hives. I took her to see the doctor and they referred us to allergy clinic but we have to wait 3 months for the appointment. So we fed her a tiny bit of yoghurt, to make sure it was the milk rather than some other formula ingredient and she didn't have any reaction. So the next day I gave her a bit more yoghurt and let her feed herself, it got a bit messy and she developed bad hives but didnt vomit. So I'm guessing this means she has a milk allergy?? Or could it be a contact reaction?
The thing is since then she's also had hives to egg and weirdly tonight peas. She doesn't vomit with these either but just gets hives, mainly where the food has touched her skin. With egg she came up in hives in areas where food had not touched though and she seems to have developed a lot of eczema after the egg. Am I causing her to have reactions to food because I'm introducing things when her immune system is already sensitive from reacting to the milk she's obviously allergic to?.
I normally wait 3 days before introducing a new allergen apart from peas which I did in the same day as egg as I didn't realise it was an allergen.
I'm a bit worried about the fact she's reacting to all these things and I haven't even introduced peanuts or fish or the other allergens yet.
I guess what I'm asking is, has anyone had a similar thing where food causes hives but not any gastro effects? And does that mean it could be sensitive skin with the egg and peas, rather than an allergy? And is it usual for a baby to be reacts to so many types of food?
Thanks for reading sorry it's so long

Ds2 would have a contact reaction to loads of food that he didn't have issues with otherwise. For years we had to wash his mouth really carefully and apply vaseline around it every time he ate, and he was still red and blotchy a lot of the time.

He grew out of it around 4 or 5 years old, and has no issues with allergies now as a teen, but does have a bit of eczema.

Ds1 had a milk allergy (very severe, ended up hospitalised), grew out of it at around 1 year old.

Well it could be that she's also allergic to these foods op? Peas are very similar to peanuts and peanuts, milk and egg are very common allergies especially in children so it could be that they have caused a contact reaction?
I would go down the allergy testing route. They'll do skin prick tests of the foods you've noticed a reaction to and you can go from there.
Dd2 has lots of allergies and it is a nightmare weaning h as your basically trying and seeing. If you search for the top main allergens you can at least see the most common ones

This website explains it all really well

Thanks so much for replying. Whatme123, how old is your DD2? I'm worried she'll not grow out of these allergies but maybe it's quite common for babies to experience reactions?
Did your DD2 have hives also or other gastro reactions? I'm quite scared to try peanuts now. It feels quite scary managing it on ypur own without the support of professionals. The wait times to be seen are so long!

Thanks CatherinedeBourgh. Did your LO get just red marks or did it look more like hives? My DD has like nettle rash style marks, red marks woth a little white bump in the middle

@madhen123 hi, dd2 is 4 now. We started her allergy journey when I tried peanut butter, didn't go well 😬 she's allergic to peanuts, sesame, they're the worst. Then she is contact allergic (burns her skin) to bananas and strawberries and then she is allergic, rash type allergy to chick peas and peas. She is growing out of her egg allergy I'd say though and can eat baked egg now.

Your best to get a gp appointment and they can get her seen by your local allergy clinic and they can test her for the common ones/ones she's shown a reaction to. Best to try the main allergies for the first time in a controlled environment, at home etc and only give a small small amount and wait and see. Take your time 😁

It varied. Sometimes it was full on hives, sometimes (when we were really careful about washing him after eating) just red marks.
