We are almost 11 years in. I have put the kit together once for my daughter, but then didn't need to use it because she came around. Just recently had the experience of putting it together for a friends child....4 of us moms of diabetics & we were a mess. We were at family diabetes camp & we got the kit put together just as the dr arrived & he administered it to the child that was having a seizure. She has had diabetes for like 6 years...it was their first glucagon experience.
