I really dislike that everytime there is an accident involving a child at Disney there are tons of posts blaming the parents.
If a child falls, when the EMTs get there the FIRST question they have is about what the child was doing. My experience in this is my son falling at Target, while standing firmly on the ground, while trying on mittens. Because the mittens were locked together, and because he was jerking away from DH at the moment (DH had put a hat on DS that was bugging DS, who was only 3 at the time, and taking the hat off was tickling him), he fell backwards with force but couldn't stop himself at all. He slammed backwards to the ground and hit his head on the metal base of a clothing rack.
The FIRST question from the Target employee, firefighters, EMTs (there were two batches of uniformed men that showed up after the 911 call and I'm not sure who was who), triage nurse, main nurse, and ER doctor was "was he standing in the cart?"
Parents do ridiculous, brain-free, things ALL the time. It's only natural to wonder what on earth was happening in that room.
My son stopped climbing on tables by the time he was 3 and we got rid of the table (b/c he wouldn't stop climbing and because we're casual people who don't need a dining table). He never climbed on a table again. But on a balcony, yikes. We have a balcony at home and even now he's only allowed out there if one of us is on the balcony OR is in view of him every moment. He's 9 now, but that actually makes things worse because he's so tall and his center of gravity is changing.
If he fell from our balcony, I would EXPECT people to wonder where I was when it happened. And that's despite knowing that being an at-home/homeschool-parent and getting everything at home done is just about the most impossible thing EVER, in terms of watching the kiddo and doing anything around the house. But still I would expect those questions.
