No more Thumb

Ely announced tonight as I was putting her to bed, that she really wants to suck her thumb but she is not going to.
Just like that.
She says it's because BooBoo (ari's mom) told her she would make her a quilt if she stopped.
I want to tell her, it's okay. She can still suck her thumb if she wants to.
But she has stopped.
Just like that.
Another sign that my baby is no more.
How can I stop the clock?
