Tips for bathing baby!

Autumn • You screw me, I screw you back. I`m a lady like that.
I have such a hard time bathing my son. He's so slippery and I don't want to sit him in his baby bath. I feel like it hurts him to sit on the hard plastic. He's two weeks old today. 
Does anyone know ways to make it easier on both of us? Thanks in advance.
