Help me PLEASEEEE!!!!

My son will be 1 oct 14, and as of the past few wks he wakes up every hr from 9pm-1am SCREAMING. I go in to his room and put his paci back into his mouth and he falls right back asleep. He sleeps in his crib, has 2 lovies and a dim orange nightlight and his sound machine. What do I do to make him stop? He takes 2 naps during the day usually about 1/2 hr each. Hes a bad napper. I’m about to lose my mind getting no sleep. Do we get rid of his paci and if so how?
