I know what it says!

Today we were riding in the car, and Aidan said, "Mom! The seatbelt thing says 'press'!"
"Wow," I said. "How did you know?"
"I just said the letter sounds, and it says 'press'!"
This was probably the first word he has read on his own outside of our homeschool time. After his success, he decided to read every word he saw on the way to Grandma's. He got stuck quickly on "Texaco" and "Capital One," but I'm glad to see him excited to be reading!
