Are you supposed to kiss your newborn on the cheeks and forehead?

Meagan

I just had my baby boy july 14th. Every since he was born, I have been kissing him on his cheeks and forehead. He is a preemie since he came early due to previous surgeries. I read a article on facebook that kissing a newborn can cause cold sores or something like that. The article was about a newborn dying from being kissed. How true is this?
