When the mascot was little, he used to get a bath, a book and a snack before bed. Any little interruption in that routine could have spelled disaster, although I don't know that we ever tested it. (He was such an easygoing baby that I am sure we could've... but I think I enjoyed the ritual as much as he did.)
Now that he's older (and is responsible for his own bathing and reading), every night around 10pm, before I wish him sweet dreams and send him off to bed, I make the mascot a cup of hot chocolate. And, every night when he comes into the kitchen to take it from me, I get a thank you, a big smooch on the cheek and a big "I love you". Those are my sprinkles-on-top.
