Wow Weazel - those kind of situations are scary.
In 2012, before I was diagnosed with an autoimmune disorder I have, myself and a friend took our kids to the beach. I was waiting in line with my son for some ice creams and I passed out. Due to the disorder I would pass out if stood still, but at the time did not know this! I did not come back around, so the life guards called 911. Everyone was amazing - when I signed out of the ambulance having come back around, I walked over to my son (6 at the time), to see him eating a hot dog and with an ice cream - I asked where he got that and apparently, when the life guard asked him if he was ok (I assume referring to his mom being in the back of the squad) he told them "I would be ok if I had a hot dog and ice cream!".
So nice to know my son was so concerned! In his defence, I was passing out a lot, and he knew that, so was kind of used to it! But, bless the hearts of the life guard for giving him a snack!
