6 months old suddenly reject pacifier

Anyone’s 6 months old suddenly reject pacifier? He’s been using the same type of pacifier since birth and he loved it. But suddenly he hates it. He kept rejecting. Either he will lock his lips or spit out the pacifier. Its so hard to soothe him now. Please dont tell me its good that he dont want pacifier, its easier to wean off. Nope, doesnt make things better by ssying that. I rather wean him off at a later stage, than to deal with a crying baby. Sometimes one of his ways to self soothe is to suck and pull his burp cloth.
