I have been trying for a month now I just gave up. I have a little fighter gets crazy when I try to put it in his mouth.

Idk how you do it, my son refused too, but I kept putting it in his mouth, and he got the hint. It took me a day though

@rachel8792, he has 3 of them and refuses to use one.

Oh girl, I about died when my son thought I was his human pacifier. I called my mom crying on day 3 when he did that, and she told me to bite my tongue (i always said my kids will not have pacis) and buy one.. well when I did, I was freed hahaha. Its such a liberating feeling to be able to walk away, and get things done while the baby sleeps
Good luck girl!
