I have kids with food allergies, celiac, seizure disorder, and type 1 diabetes. This transition is a process, not an event. I carefully planned the transition over years. For the diabetes, that meant meeting with school nurses and teachers to explain what we were trying to accomplish each year in terms of steps toward responsibility. I expected mistakes and omissions along the way, so I would say having a training wheels period is helpful. No offense, but if you had possession of his EpiPen during school hours, that may not have been a training wheels situation.
For food allergies or celiac, once the kid was admitted, he met with the disabilities office and we met with dining services. They explained that there were menus available online, that measures were taken to avoid cross-contamination and where that was not safe, and offered to make meals in advance that were safe, with a phone call.
Much of this involved the student him or herself checking online, making safe choices, or making the phone call for an advance order. So it isn’t just taking responsibility for the EpiPen that is needed.
I have to admit, my son wasn’t always compliant with his EpiPen but there wasn’t much I could do honestly. He was aware of the risks. I gave him the proper training and time to take it on and accompanied him on meetings with the college but after that, it was up to him. I do not feel it is proper to limit choices based on a disability, but that’s me.
I would suggest that your son meet with an allergist who can urge him to take the EpiPen with him and explain why. I would suggest that you begin an accelerated process of disengaging. It may be that he has coasted knowing you are involved, or that he is somehow asserting himself by forgetting so to speak. Or he is just a young person in denial.
In any case, it is very important for him to avoid exposure, and I hope he is well-informed on that. EMT’s have epipens and although I know things can happen fast, that is an improvement.
I live with risks for my kids every day. It is hard. But they have to grow up and believe me, perfect compliance is never possible.
