This is 100% NORMAL puppy behavior. Laying him on his side may not be the answer. When he does this, act as if you are hurt, then ignore him. When he settles down, then on with business. He will outgrow it if you don't accept the behaviour. But again, I have to say, that this is normal puppy behavior. The only thing I did with my little girl when she was in this stage, I would yelp like I was hurt, then turn away from her, if she got her little razor blades on me, lol. Just be consistent and persistent and reward him when he behaves in an appropriate manor, and you will see the changes.
