Here's a really cute idea. Frame quote bubbles, use a dry erase marker to write funny things your kids say. When you are ready to switch the quotes, have the child take a picture with their quote and make a photo book of quotes.
Kids did this in Kindergarten...they LOVED it! Draw on sandpaper with crayon, turn upside down, iron onto T-shirt. how proud will kids be to wear their original art designs! This would be a fun idea for a birthday party
