Great story Michelle, i hope mine will end that graciously.
Basically, my daughter still has a dummy to sleep, NEVER, out of bed, and she is 2 and 9 months old. Hers are so worn and old i am sure she will hand them over herself. I have one emergency one in the cupboard, but she can stick with the ratty ones as far as i am concerned.
I new before my son was born, i would keep everything as different as possible, so his dummies were a total different brand. She only tells him that dummies are for sleep, and has never been interested in his.
Best of luck,
I guess this doesn't help your actual question really, :~
