Perna - sorry if my mentioning about dirty fingernails triggered this memory.

You know what's strange - just as I'm typing this my 8 yr walks up to me and says "look mommy how I let all my nails grow" lol. She's doing so well in stopping. When I told them about how nails can be germy, I didn't say it meanly, just casual facts and sharing. Then I taught her how to be mindful of when she brings her hand up...like when she's watching a suspenseful TV show etc.
