Reilly can read??

This morning I am wearing my Halloween shirt (see pic below) (yes, I'll wear it tomorrow too - don't judge me!). As I am getting Reilly ready, she looks at my shirt and says, "Mommy, that says Boo!" I about jumped out of my skin. "How do you know that?" I say. And she points to it and says "B -- O -- O...that spells Boo." She said it so matter-of-fact, like Duh Mom!! I knew she knew the letter B, but I had no idea she was starting to put the concept of words together. I asked how she knew that and she said "Mrs. Bogart taught me!" Hurray to Mrs. Bogart!!
