Where is it normal to go to the emergency room for any old fall with no obvious injuries? Around here unless there's an obvious break or concussion, or the kid is obviously in extreme pain when a lesser injury would have begun to hurt less, then they would usually just keep an eye on them or book a doc appointment for something in the middle, and I live in the UK, I'd have thought people in the US (if that's where you are) would be even more resistant to getting a $$$$+ checkup at the ER for something that's going to happen to any kid dozens of times throughout their childhood, is a normal part of learning coordination, and for most kids never results in a serious injury?
