Actually, most kids do NOT lose the non-nutritive sucking need until 18 months old.
I don't agree with taking it away...especially if she is attached for comfort and can't understand why you are taking it away. My kids will keep it until they give it up. If by 5, it isn't gone, then, they are old enough to understand and discuss why they have to give it up. Most kids WILL give it up by 3 or 4. It has been shown to not affect teeth until after than as well. Give her time...
