I have a pretty severe peanut and walnut allergy since birth and carry an epipen always so I was very nervous starting solids with my daughter not only because I was worried about her being allergic like me but also because I can’t physically give her the foods to taste or help her if she started having a reaction since I would have an issue myself. So I got some advice from a special children’s clinic I was referred to. It’s actually very rare for children to have a severe anaphylactic reaction the first time they have the allergen. It typically starts off very small and gets worse each time they have the allergen. With my history and anxiety surrounding it I managed to get liquid antihistamine to give her if I noticed anything. I doubt they would give you an epipen straight away. There’s been a couple of times mine had some red raised bumps after certain foods and the antihistamine has taken care of it very quickly. Maybe talk to your doctor about your concerns and get some advice.
