They fall outta their mouths constantly, landing on the dirty floor or plain dirt if you're outside. If you get your baby hooked on a pacifier it is just one more thing you have to take away later on when they're too old for one. That is, unless you're like many parents I see around town, pushing their fat 5 year olds around the mall in a stroller while he's steady sucking on his "binky", then your kid is never too old. Lazy parents. Sorry, this is a subject I DO get judgemental about.
My main reason for not using a pacifier is the fact that it shuts the baby up when all they're trying to do is communicate with you. If a baby is crying, we all know that means they need something. A pacifier is something artificial that sometimes makes the baby think his needs are being met. I think it's fine to use it once in a while (like at a doctor appointment when he's getting shots) but I disagree with it being used constantly. A baby deserves more than that. After the baby becomes dependent on the pacifier I think the parent has created a monster. The baby isn't happy without it. He'll cry if he doesn't have it, even more than he cried before you got him hooked. He isn't learning to self-soothe and he's probably not learning to communicate. Judging from the toddlers I've seen who love their pacifiers, they turn into little big babies.
Ugh, okay, I got it off my chest.
And now some pictures!
