Hi girls, I have a question: who has their baby stopped using a pacifier?

Hi girls, I have a question: who has their baby stopped using a pacifier? I already regret giving my child one, they're 7 months old and we haven't been able to sleep without a pacifier for a year and seven months. We tried to wean them off with grandma's advice and some breast milk, but I don't think it's the best method.
