Dd wants to break her habit of picking, biting and tearing at her nails. We have tried rewards, star charts, reminders, one finger at a time, bitter stuff, everything we can think of, but it's not working.
Yesterday I was admiring my aunt's beautiful nails and she told me that she had worn false nails for about a year, and when she stopped having them she found that she had stopped biting them, too.
So I wonder whether this could work for dd? Obviously they wouldn't be long, and would have neutral polish.
