I think you just did “bottle it up to keep forever” as you wrote it down. Keep this story in a special place where you can pull it out and reread it and all of the other precious things your children say or do that you think you will “never forget” Write them down! The memories will be just as sweet, the same smile will come to your face and your heart will be filled with the same warm tender feeling 30 years from now every time you reread and remember that night when your son asked you for more “Mommy cuddles!”
