I was posting like this a couple of weeks ago!
Our Sonny is now just coming to 12 weeks. I had the same problem and it was driving me mad, I had expected it, as its completly normal, but didn't realise the extent of it and how much it would drive me nuts!!!
Sonny has improved greatly and now understands NO. My advice would be to be consistant (as rainy says). You may feel like nothing is working, but as they continue to grasp life around them they soon realise that its not welcomed. Sonny still has his moments - at the moment when I am trying to put his collar on! But has inproved massively.
I have used the pet corrector, and for me, it seemed to work. But can't stress enough, this has to be used correctly and not abused. I have used it on sonny only 3 times now, and it seemed to have a good effect - and I have only used it for the nipping.
It really does get better, and probably your thinking "I can't see an end to it!" - like I was a few weeks ago, but trust me, it will not be as bad soon
