Just a thought chody, does she still go to daycare? If so, does she still have a dummy there?
She does go and I do send one with her. She rarely sleeps there anymore (she rarely ever naps), but if she is tired then its there or, on the odd times she gets really upset (the other week she came down with an ear infection whilst there) they help to calm her. I'd feel bad for daycare if I didn't send any with her.
