I bought a book for Ethan entitled, Baby on the Way, by the Sears. It is a little too mature for him. I think it is meant for 2.5-5year olds. I spend most of my time pointing to the people in the pictures and explaining the pictures. Today after we "read" the book, I say,
"Ethan, mama is going to have a baby. You get to be a big brother. Would you like to be a brother?"
Ethan claps his hands. "Yeh."
Oh, good. That is a relief. I was kind of worried about it.
