When did you guys know to change pacifiers to the 3+ month old ones? My baby is using one right now and she’s 10 weeks, but they’re firmer than the newborn ones. I don’t want to hurt her jaw or gums because of the firmness. But she took it and didn’t spit it out or anything, and she would spit out or suck too hard on the newborn ones they would fall out of her mouth. Does that mean it’s okay to use the ones for 3+ months now?
