i breastfed both of my babies. and neither of them took a paci. they just hated them. never took a bottle either. so maybe they just prefered the breast. my son nursed a TON an then would spit up a lot, but it never seemed to bother him like reflux does. i know with my 2nd i waited much to long to introduce them so that was a problem.
BUT
there was this video we watched called"the happiest babay on the block". it was super helpful for the infant stage. i'm not 100% behind the philosophy, but it gives you some Great tools for calming a fussy baby.
one of his suggestions is a paci. but he mentions that babies need to be trained to use them.
they dont know how to keep this non-milk giving object in. so when you give your infant son a paci you cant expect him to just suck away like on your breast.
his advice is to NOT keep pushing it in. but rather to lightly press down on the top of the paci... like you are going to push it out of his mouth. he will react by sucking harder to keep it in, and you can train him and make him stronger by playing this game.
i have done it with other children whom i watch and it has really helped.
worth a try anyway.
