"H" and "A"

Today in the nursery, Christian was playing with the wooden blocks. I was working with some other kids when he said, "Look, Mommy! The letter H". He made a letter H out of the blocks all by himself. An older boy thought he said "A" and said, "That's not an A". Christian looked confused at the boy's comment. I told him what a good job he had done and we all moved on. A few minutes later Christian said, "Look Mommy! The letter A". He made the A by himself, too! It's the first time he's made a letter by himself. I'm so proud of him!
