Cary also has a scar on his eyebrow from his grandma (my mother). He was reaching to play with a glass cocktail shaker when his grandma spotted him doing this and panicked that he would shatter it and cut himself (it's a thick glass shaker). So she lunged for him, and tripped, and crashed into him, slamming his face into the edge of the shelf where the shaker was kept. He bled a bit, cried a bit, and grandma was also upset. His eyebrow now has a permanent "crack" in it.
One of his aunts has also picked him up by his upper arms (with his arms by his sides, not over his head) to...put him in a chair or something (don't remember) at her daughter's b'day party when he suddenly started screaming and squirming and nobody could figure out why until she realized she was still holding the Bic lighter she'd used to light her daughter's candles in her hand and was now pressing the still-hot lighter into his upper arm while she was holding him. That scar has faded to invisibility.
He has also been caught playing around on the bed in our bedroom (which he knows is off-limits) when he suddenly started screaming. He likes the glass beaded shade from the light on the bedside table, which has a candelabra-style 40W bulb underneath it, and since he had taken off the shade, the bulb was no longer covered. So while he was rolling around on the bed, his ankle came into contact with the bulb. He still has a scar on his ankle that's pointy on one end and looks a little like he's had a tiny little clothes iron pressed against his skin.
These things happen. So long as they're not fatal or disabling, they're part of the learning process. For kids and parents.
