Ds has just turned 4 and is allergic to nuts. I'm wondering at what age it would be safe (and fair on the other parent hosting the play date, party, etc) to leave him anywhere without me or his dad. It is quite a bit of a responsibility. He is too young to expect him to understand the symptoms of a serious allergic reaction and i dont think he would be able to inject himself with his epi pens and call or ask someone to call 999. He has been going to nursery but I think that's different because they are first aid trained and hopefully know exactly what to do.
It's already awkward having to inform other people wherever we go of his allergy and cross checking ingredients of anything he is given to eat.
What do other parents of kids with allergies do? At what age was your child able to handle their allergies without adult support? At what age did you allow them to be supervised by other adults untrained in allergies? Did you give these other adults spot training on how to handle their allergy?
