Hi Bobbie! We just successfully weaned our 18 month old off her pacifier so I'll share what we did. But, Zoe was a year older so I'm not sure how this would work with a 6+ month old. About two months ago we attached the pacifier to a small (about 8 inches) stuffed animal with a hair tie. (I'll send you a picture if that would help...just be careful there's not a string loose/choking hazard.) We continued giving Zoe the pacifier but she was required to hold onto the animal if she wanted to suck.
First, she realized that she couldn't play if she had the pacifier in her mouth. It limited her to one hand so she began losing interest but still wanted it at bedtime. After a few weeks of her having it whenever she wanted, we limited the time to bedtime and naptimes. We did that for about a month and when we got her in the morning, even said "Drop the duck" so she knew it stayed in the crib.
Just over a week ago, she fell asleep in the car withOUT the pacifier so I transferred her to her bed when we got home and decided it was time to end the pacifier. That night, I rocked her to sleep without it and she hasn't had it since then.
Some people might detach the pacifier from the stuffed animal because the child has associated comfort with it too.
Just our experience with the whole thing and so relieved to have ended her addiction. Good luck and let me know if you have more questions!
