So my daughter has been of the paci since she turned one which has been about a year now. But lately she’s been putting her brothers paci in her mouth lately 😭 I tell her that’s ewww and it’s only for babies but she insist on keeping it in her mouth . When I take it off of her she’ll scream for a few seconds and forgets but I do not want her to go back on it!! HELP
