I'm sorry that happened! It does sound scary.
Continued oral steroid, if that were my child, would feel like over-kill to me. If they were concerned about anaphylaxis you should have been prescribed an epi pen (ideally) and referred to an allergist. Oral steroids are hard on the body. A short course, which this would be, won't have long term effects but it's not something you'd do unless you must. Both of mine have been on oral steroids when needed. They are sometimes needed but I don't think I would continue their use in this case unless you see continued reaction. Having said that, it's hard to know what's going on in a child that young; maybe that's their thought process.
I would want an epi pen. My guess is you have a pretty significant sesame allergy. Sesame is as anaphylactic as tree nuts. It has a shared allergen with tree nuts (pistachio and cashew) and mango. Those are high anaphylaxis potential allergens. My son is anaphylactic to all of them. Until you talk to an allergist I would avoid tree nuts, sesame, and mango. Hopefully it isn't that of course but I think you need to know given the severe reaction.
Hives are usually well controlled with Zyrtec. I'd do maximum dose for his age for two weeks. If you see any other reactions or the hives return while still on Zyrtec give the oral steroids and seek help. Otherwise, I don't think you'll need the steroids. My son has needed them for severe reactions but those were worse than this one.
Read up on signs of anaphylaxis. Call his regular doctor and see if you can get epi pens (you want two; they come in two packs and that's the most common type of prescription but some doctors don't know that you might need 2 in a single reaction) and referral to an allergist.
Hopefully all my advice will turn out to be unneeded when you see an allergist. But I really think you've got a serious allergy to something and sesame is the most likely unfortunately. My son does really well--even if it's that it's not the the worst ever allergy set once you get adjusted.
