Try putting a burp cloth between you and he. It'll save your clothes, and it is a good, temporary solution to a problem that you and he will grow out of. As he gets longer, you'll find that his head starts to push into your chin... which is cute, until he starts to do the woodpecker manuever with his head into your face (tears all around). This will drive alternate carrying solutions.
Steadman is right on. It also won't be long when he won't want to be facing you, but facing out. This usually happens when their neck is strong enough to support their head. And, by the time they can sit up, then you want to carry them on your back because they are so freakin' heavy.
