You're right, I'm always surprised when I see parents carrying their kid's scooter or bike back from the park. How do they instill grit in children if the "hard part" of things are always done for them (assuming of course the child is actually capable of doing such things). Now they shouldn't flat out call the child lazy, that harms self esteem. But it should be clear that their child is expected to bring home the scooter they were just so happily riding around on.
