3 yr old daughter and binkies

Hi ladies, so I have a huge problem. My 3 year old daughter is addicted to her binkies. I used them as a bribe when I was potty training her because her poop hit the toilet weird and she got splashed in the butt with toilet water. Now she won’t poop or really use the potty without a binky in her mouth and even then she still asks for a diaper which is getting hard because her size 6 disposable diapers are getting tight. Please help me!
