SO doing this for my kiddos someday... send "Oh, the Places You'll Go" by Dr. Seuss each year on the last day of school. Don't tell your kids and let them read years of messages on their graduation day! I started this with Bryce in playschool last year.
Brownie in a Cup ~ Wipe the outside of the cup with rubbing alcohol. Use an oil based Sharpie paint marker, then write the instructions onto the cup. Let the Sharpie dry completely for 24 hours. Place your cup in a cold oven, then bake at 450 degrees for 30 minutes. Crack your oven door and let the cup cool down with the oven to prevent cracking. This would be great as a gift, add the dry ingredients and wrap.
I'm a big fan of this breakdown on Santa. I appreciated the idea behind Santa as a child, but this letter from a child's parents just smashes the nail on the head for me. I dislike the idea of "robbing" the magic of Christmas from my children with "the truth", but with a message like this I don't feel as though I have to anymore. Awesome.
