Reluctance to part with that first loose tooth is the problem of Little Rabbit, who jokes about the ""window"" in her mouth but thinks she'll keep the tooth instead of leaving it for the fairy. After trying in vain to think of some use for it though, Little Rabbit relents, becomes more interested in the dime that will replace it, and, at bedtime, speculates about what use the fairy might make of her collection. This is another of those fictional specifics to be dispensed as indicated and forgotten with the patient's own lost tooth--that is if children old enough to lose one can accept De Groat's too toothsome rabbits and their cozy-cute domestic appointments.
