What kind of pacifiers work best for a 2 month old?

i have tried the newborn blue ones, the gerber sids reducer,and the round ones with the flat tip. my 2 month old son doesn't like any of them. what kinds worked for your babies? he also has tongue tie, where the thing under your tongue is to tight. he only sleeps with my nipple in his mouth and as soon as i take it out he wakes up.
