My twin daughters at about two years old. They’re a pretty close match but not identical. People often used to think they were, and were always getting them muddled, but really if they had taken the time to look properly they’d see many differences. For instance, I could tell them apart, even from behind, just by the shape of their heads!
Amazingly to me, they will turn 30 this year, and though they live at different ends of the country, and have had different experiences, they are still the best matching pair I know!
