Since then I've started to put together a "go kit" for my son with one or two days worth of meds and some safe food in it to keep near the door along with his EpiPens. It's still a work in progress and will require monthly mainenance to exchange the medications for new ones so they don't expire, plus switching out the snacks so they don't get stale and nasty. I'm using the medication bottles from the previous month after I refill his prescriptions, to make sure they have the original labels on them.
I still don't have a satisfactory container or location for the emergency kit, and I haven't made final decisions on its contents. If you have something similar prepared, I'd love a comment describing it.
Hopefully your holidays have been both uneventful and joyous. Here's wishing all of you a safe and happy New Year!
