Wow!!! So glad things turned out okay for him and you! YES, I would be concerned over liability. I only temp took care of a child who suffered from seizures, luckily she never had one in my care though. The mother provided an epipen to stick in her thigh and informed me to immediately call 911 IF she went into one. I was asked to take her full time and declined (she also had autism and didnt walk, got into everything) too much work.
A few years ago I had a little baby choke (on his own snot) at the time I didnt know what he had in his throat gagging and gasping for air, scariest situation ever, did infant back thrusts and called 911. in that moment so many thoughts went through my head, what if he dies? what will happen to me? my daycare? my life? doesnt take much to lose it all when we are in this job, the liability is extreamly high. There is so much at stake when you have someone elses child in your care. so glad everything turned out the way it did. The one thing I got out of the experience was...I could use my training and save a life.
