Peanut reaction?

48 replies

OnNaturesCourse · 24/06/2025 12:30

4yo DC was given peanut butter today.

Never had it before and I don't believe there has been peanut exposure before (I know, I know...)

Theu didn't like it and fussed abit about wanting to spit it out but did swallow it. Took a breath or two and forcefully threw it all back up. Maybe five minutes later was sick again bringing up their breakfast this time. Is now saying the sick made their mouth feel "tickley" but is otherwise absolutely fine.

Could this be a very mild reaction? Is sickness a symptom? I was leaning toward the first sickness being because they didn't want to swallow it but after the second lot and now the mouth I am wondering.

That's odd as I was told by paediatric dietitian to give exposure as soon as possible after they flapped that my, then just turned 6m old, child hadnt been given nuts

How times change. When all mine were little, you were supposed to have a nut free/ peanut free house.

Few points

DC hasn't been exposed as they simply won't try a lot of foods due to having quite a restricted diet growing up (milk allergy, lactose intolerance) They are very cautious with new foods. Hint why I didn't think much of it when they suddenly wanted to spit it out, this is common here.

I can't go private for a allergy test but will inform GP.

No further reactions since post.

No skin reaction when the peanut butter was applied (as advised)

Who advised you to put peanut butter on the skin?

“I know I know”

If you know I don’t understand why you’ve waited so long to expose your DC to nuts. It’s well documented exposing them at a young age (6 months +) reduces the likelihood of an allergy.

Give it a rest. I can’t stand peanuts and we don’t have them in the house. My daughter has never eaten them because I didn’t try and now she absolutely hates all nuts too.

WhatMe123 · 24/06/2025 19:31

Yes sickness is a reaction. I mean they're had a mild reaction but when dd2 first had peanut and we had to phone an ambulance, her whole face swelled up she was vomiting everywhere and the paramedics said it was a good sogn as her body was getting rid of it so yes it can be allergy

GloriousBlue · 24/06/2025 19:35

If he's got a milk allergy, his risk for other allergies will already be higher.

It sounds like a typical allergy. My son has had vomiting as a reaction sometimes (and other times hives or a rash).

Contact GP, request tests, get Epipen, avoid peanuts, look into immunotherapy if allergy is confirmed.

@1HappyTraveller it was the hospital team

Yes that sounds like how my DD is. She is allergic, if she does accidentally eat peanuts it’s “my mouth is itchy” followed by nausea for a few hours and possibly vomiting, depending on how much she has eaten - but she wouldn’t eat a lot because she can tell the second she puts it in her mouth.

My ds also

Lavendersong · 24/06/2025 21:21

Sounds like he is sensitive to it

But will need an EpiPen regardless because people in the past with only a sensitivity to nuts have suddenly reacted badly and died

So treat it as an allergy for now and avoid nuts till assessed further

Lavendersong · 24/06/2025 21:25

There was a case in the UK recently where a young lady was only sensitive to nuts thus far so when she had a reaction in a restaurant the parents didn’t call an ambulance but the mum went home to get the EpiPen.

The young woman died
Never underestimate the power of a nut sensitivity/ allergy. Be prepared no matter how mild
Always be very very careful when eating out.

Lavendersong · 24/06/2025 21:27

avoid oils like sesame seed oil.

avoid nuts and seeds for now

FreyaW · 25/06/2025 06:38

Yes. It's a common first reaction. Recommend getting an sppointment at an allergy clinic for testing. Second reactions are often worse than first. Avoid all nuts until further notice.

OnNaturesCourse · 25/06/2025 09:11

Advice given has been "try again" and observe the reaction 🥴 might just park up in the hospital car park beforehand!!

Who did this advice come from?

GP, nurse, PA?

Give it a rest? Why?
We know that early exposure reduces the risk. You decide not to give your child nuts because you don’t like them. What you aren’t considering is that your child will still come into contact with them. Avoiding things because you as a parent don’t like something isn’t helping your child. I’m gathering by your post that your child thankfully isn’t allergic but merely dislikes them. But an allergy could have occurred with late exposure.

TBC45678 · 25/06/2025 10:01

@OnNaturesCourse I really wouldn't recommend doing that. What you've described is a fairly severe reaction and as people have said above, subsequent reactions are often more severe than the first. I'm not sure who is advising that - our NHS allergy team (consultant and dietician) has always advised us to avoid a suspected trigger until it is confirmed/ruled out via skin prick, and I'm sure your GP would say the same. Even with an epipen this would be very risky. If your child doesn't like it anyway I don't see the need to give it another go, just wait for an allergy testing appointment in hospital.

TBC45678 · 25/06/2025 10:21

And maybe don't take too much more advice from whoever has advised you to give it another go and try putting it on their skin - neither of these ideas are sound medical advice! A contact reaction from putting it on their skin would not really tell you anything.

OnNaturesCourse · 25/06/2025 10:37

It was the ped dietician at our local NHS hospital team. The info was given to the ped doctor we see and passed on.

I have a child with a severe allergy to peanuts.

Request a blood test and skin prick test asap from allergy clinic in hospital. Absolutely do not let them try peanut at all, again. Remove peanut products from your home. Tree nuts are “may contain” peanuts from most Supermarkets apart from a specific brand in Sainsbury’s. Peanuts are not nuts, they are legumes. Your child may also have an allergy to tree nuts or they may not. My son is peanut only. If blood test and/ or skin is positive then you’ll be provided with epi pens.

You may well wish to be vigilant about all other items you buy and check packaging. Lots of parents who have a child with peanut allergy avoid all products that have “may contain” peanuts on the packaging. It is very overwhelming at first but it does become second nature. You learn what’s safe and what isn’t. You learn which brands you must avoid completely. Some brands do not differentiate between nuts and peanuts so they are avoided by us (and many allergy families). You learn where is safe to eat out and to check allergy menus.

TBC45678 · 25/06/2025 10:42

I'm so confused by that! So are you already under an allergy team at a hospital? As far as I'm aware a contact reaction (which could occur to something on the skin) will give no indication of a food allergy, and we've consistently been told to avoid a suspected trigger. When they do food challenges (as it seems you're being advised to do by trying it again) it is in a hospital room overseen by medical professionals with access to instant adrenaline.
I guess follow the medical advice you are being given but just saying that it goes completely against what we've been told.

OnNaturesCourse · 26/06/2025 07:10

Not a allergy team, no, but a paediatric dietitian team due to ongoing intolerances with child and siblings.

My partner vomits as a response to nuts he is allergic to, together with the tingling and he gets some wheezing etc. He's never eaten enough to really see what happens, but likely anaphylaxis if he ate enough, but the tingling means he knows pretty much instantly.

TBC45678 · 03/07/2025 20:25

@1HappyTraveller God this is horrifying. My son's reactions and overall health sounds so similar to this poor boy. It's so easy to downplay allergies, even in your own home (I've been guilty of it), but we've been told time and time again by our doctors that one reaction is no proxy for the next - i.e. just because there's no anaphylactic reaction to a trigger one time, there won't be the next time. This is a horrible but important reminder.
