pat the bunny

We've established a night time routine of cold milk in his sippy cup, reading a few books in the rocking chair, and a little cuddling while singing a song or two before laying Callen in his crib for him to fall asleep on his own. The last two nights in a row Callen has wanted to read Pat the Bunny before bed. We get as far as Pat smelling the flowers, then we smell the  flowers and Callen is out in the processes of sniffing! He presses the book to his nose and just smells and smells. The flowers aroma must have a sleep-aid in them.
