My daughter didn't get introduced to pacifiers until she was over two weeks old. I didn't want nipple confusion those first few weeks of breastfeeding. now she takes them but only sometimes thank god she don't rely on them..
I give my little girl one but only because she Sucks on her arms so hard she leaves msrks
I never gave my son a pacifier. I felt like I didn't want to give him something I'll eventually take away.
