My GSD nips only me! HELP!?

My puppy is currently teething now too and I had the same problem. I found that the best way to stop her was to firmly say "NO" every time she did and spritz her with water. Eventually just saying "NO" stopped her in her tracks. There are also plenty of chew toys specifically made for teething puppies, and having them around the house also helps. It's only been a week but she now only nips when she can't find her chew toys, and usually only once to get my attention.
