Wanted to share, while I'm not a fan of using a pacifier this young, my son is 3 weeks and 3 days, it worked like a miracle this time. He was becoming fussier these past few days. He was fed, changed, held, comfort nursing- breast and bottle but would just cry. We didn't know what to do except let him comfort nurse or keep feeding from the bottle while holding him (sometimes walking, rocking, swaying, etc) in hopes he would calm down. My husband out of desperation put the pacifier in his mouth cuz it seemed to calm him when he sucks on our pinky. Needless to say I am very pleased with this result (even tho I don't initially approve) as I was at my wits end.
