I have been talking to her about preschool. I ask her what she is doing in September and her excited response is "two-year-old class" - which does require some interpretation for the untuned ear. She knows her teachers names. I ask her what she gets to bring to her 2-yr-old class and she shouts - BOOKBAG!
This is one way I figure she can visually understand the difference between MMO and preschool - because they are at the same place. She will continue to bring her tote bag to MMO and then a bookbag to preschool. Enter new bookbag. LL Bean has the best bookbags from way back - I still have one of mine from high school (gasp). So I show E the backpack options and not to my surprise she goes for the pink polka dots. She makes me smile.
