In an attempt to generate enthusiasm over the mundane stuff of life, I have started saying things to Roxi like, "Melissa's coming over! Isn't that exciting? I'm excited, too." or "We're going to change your diaper and then go to the grocery store! Won't that be fun?" It seems a lot less ridiculous when I'm saying it to a 20-month-old than it does now that I see it in black and white, I assure you.
Roxi, being no dummy, has started to use these phrases to her advantage. As in: "Listen to Cuckoo song. I'm excited too!" and "Have graham cracker. That'll be fun!"
