You would think that people are on stairs only a few times a day and it wouldn't happen very often, but his happen when he cries and kids actually do kind of cry a lot on stairs.
A week or so ago, after plenty of fair warnings about not dawdling over his dinner, L was left to finish at the table alone, much to his distress. I went upstairs and he started to cry, and I guess he felt himself starting to go into that mode. Instead of lying down in the recovery position, he tried to get upstairs for help. And then he had the seizure on the stairs, thankfully at the bottom.
A few weeks before that we were all sort of doing our own thing around the house, I don't remember what exactly, when L suddenly realized he was alone downstairs and it scared him. It's one of those things where it could happen a hundred times without triggering one, but this time it did. Again, he tried to race to find someone and ended up having one on the stairs.
The answer here, of course, it to teach him to put himself into the recovery position, no matter what, but how? The only thing he wants to do is get to me.
