Sounds like you just need to ditch it crumpet. If she's not using it from 10ish pm onwards, and sleeps right through, dude, you are on a good thing. She doesn't need it.

Give it the flick.

Do what I did - go cold turkey. Throw them all out (even the ones that have fallen down behind the cot/change table/couch) and just suck it up for a few nights and you'll be fine again.

I do hate the photos of DD that I see with her dummy in...
