To use a pacifier or to not use the pacifier

My daughter is 3 weeks old. She had trouble in the beginning gaining weight because my milk didn’t come in right away (she’s doing great now though thankfully). I’m EBF but she gets a bottle of pumped milk sometimes at night when my husband gives me a couple hours to sleep. I’m noticing that sometimes she comfort feeds, which isn’t a terrible thing, but I’m going to have to go back to work when she’s 3 months, and I’ve heard the trouble with trying to break a thumb sucker. Just wondering how everyone is handling the paci issue
