Why dont wana use pacifier?

Yes, its quite hard to get rid of the habit of using pacifier as they grow up. But at least it is more hygiene than sucking their fingers.

But it does not affect the growth of the teeth nor the arrangement of the teeth.
My elder and 2nd daughter used the pacifier when they were young. They have neat teeth arrangement. Where else my youngest son never used pacifier and his teeth arrangement is quite awful. And he has the habit of biting other kids during a scuffle <shake head>.
