Emma completely understands the calendar and knows the months of the year and how far apart each month is, so a couple of weeks ago I told her that IN JULY we will be going to Grandma and Grandpa's house. Apparently in her mind, today is July!
This is the exact reason why last year when we took her to Disneyworld, we did not tell her where we were going until we actually got to the hotel! We knew we wouldn't hear the end of it until we actually got there! After all, Disneyworld is the motherland for Princess Emma!
