I am repinning this site for you guys that still receive tooth fairy visits :) Incredible ideas here!! And one of my own: I used to use extra fine glitter (fairy dust) from Michaels and sprinkled it around on the nightstand with little "footprints" (from my pinky finger). The looks on the kids faces...priceless!! Sean and Joshua still remember it, all these years later!
Take a picture on their first day of the school year, frame it and then take a picture on their last day of the school year holding the first picture ... I also love the idea of graduation day holding the first day of kindergarten!
