My husband has a ridiculously large head. When he was a child, his hair was very red, so his brother tortured him by calling him "Pumpkinhead" to make him cry. He owns very few hats, because standard sizes don't fit him. My oldest daughter inherited this trait. When she was little, she rarely wore turtlenecks because it hurt her for me to pull them over her head. I could wear her hats when she was only 8 or 9 years old.
