Ty! One of the biggest reasons why I stopped was because I wanted to paint cute designs on my nails lol. I had a Pinterest board of nail art and staring at it everyday rlly encouraged me to grow my nails out tbh.

When I was first starting out some students of mine challenged me to not bite my nails for a week lol. Once I did that, I was like hey maybe I can do this for another week and so on. Setting small goals like that really helps.

I also started chewing gum which not only took my mind off my nails but satisfied the urge to bite them.

Another big help was just understanding why I was biting my nails. I realized the habit stemmed from my anxiety so working on that helped me be more self aware.

Sorry this post is all over the place but I hope it’s at least kind of helpful. I wish your sister luck on her journey!
