Newborn is sniffling what can I do?

My nearly two week old has got the sniffles. I'm full of cold so I'm assuming it's what he has. He was born at 37 weeks so I'm a little worried he may not be good at fighting it off. He is ok other then that but he does sleep up to 22 hours a day!! Not sure if that's normal???? He's been like this since he was born.
