Refuses pacifier

Tiana • Happily married💍 Mommy to a cub 🦁
Any tips or success stories on getting LO to take a pacifier? 
 
He used it in the hospital, but  now he doesn't know how to keep it in his mouth...nor does he want to. When I introduce it to him he sucks for a bit(with the help of me keeping it in place for him) then gets frustrated because it's not my breast(I'm guessing).
 
Is there anything I can do or is the Paci just hopeless?
