I thought up this idea for lunch for R and I:
Take a hot dog bun and place in it a banana instead of a dog. Use peanut butter as "mustard" and dried cranberries or strawberries as "ketchup."
Despite R being very excited to make his Banana Boat, he wasn't that into eating it. Hmm. I chalk it up as just a typical preschool idiosyncrasy, so I will have to try it again. But perhaps a fun idea for you to try with your sweet peas.
