What did she just say????

I have to share this.  I'm still flabbergasted.  We were all driving in the SUV today.  Maelie's in the back, in her carseat, of course.  Back there, there is a set of Mickey Mouse board books, and, to clarify, her and I haven't read these books together.  She's just been enjoying 'reading' them on her own.  I may have read this particular book to her once, but, honestly, I'm not even sure.

Anyway, from the back, I hear her 'reading' her book, BUT....she's saying a particular word.  I looked over at Mike and asked, "What is the title of that book?"  Sure enough....Maelie was SAYING the title of the book.  "Shapes."  Clear as a bell.  "Shapes." My jaw hit the ground.  HOW DID SHE READ THAT?????

Even if we have read that book together, I am certain I did not read the title of the book out loud.  I never do!  And, oddly enough, when we practice our shapes, I never call them shapes, I just call them by name.  "Maelie, can you show me a circle?" etc.

So, the mystery of the day is....HOW DID SHE READ THAT???????????
