M.W.
Just throw it away. It causes them to be upset for a few days and then its DONE.
Having it at nap and bedtime at this age is not horrible, but its getting to a point where she's too old for it. I took my daughter's away at 18 months and she was fine with it, not even asking for it. But then when she started teething for her molars I gave it back because she loved to teeth with it more then sucking on it. She got back into the habit of needing it, so she was over 2 when we finally tossed it. All the teeth were in so no reason to have it back. It was one or two days and then no more issue.
Best wishes!
