Larger pacifier.

Any suggestions on transitioning to the next size up pacifier? We are currently still using the 0-6 month ones because my little one refuses to use the others. She is 7 months old and instantly spit it out. 😅 we usually offer it a few times a day, but no luck. We’ve tried the same brand that she’s currently using as well as a bunch of others that we have from her baby shower.

is there any trick we are missing?
