Help?!

Shelby • ! My oldest is two born {1.17.14} & my youngest was born {2.16.16} blessed mommy of two beautiful baby boys!
So my son is 10 days old. And of course I'm going to call the doctor as soon as they open but his right eye is always madded shut I have to get a wipe and wipe all the gunk off in order for him to open his eye. Its all red and stays gunky. Does anyone have any idea what it is? He dont act like it hurts him he does not cry when i wipe it or anything. He's not running a fever or anything like that! Anyone have any idea what it could be?!
