How can I make my baby kick the licking habit?

You won't stop this because it's a perfectly normal part of baby development. I know it seems weird but babies explore the world via their mouths so to stop this would be to stop your baby from developing normally. All you can do is make sure dangerous objects are kept away from her. Let her lick safe objects. This will eventually p when she becomes a toddler so don't worry about it at all.
