Stinging nettles punishment

I was so nostalgic, I read some old post here written by me. I noticed the nettle punishment 5 years ago as top of punishments. In that time I only read about it. Now I use it on my daughter with great success. Thanks for the moms who helped me about how I introduce it in my household. If you use it for punishments or got it from parents, do not hesitate to share with us your experiences.
