I'm a bad mom

So, I could go into a really long explanation about why I think I'm a bad mom, but it really boils down to fixing the following issue:

A: I need to find a way to get some more sleep.

OR

B: I need to stop walking my newborn son's head into walls. And bumping it on his crib when I pull him out. And knocking it into stuff when I put him in. And dropping cell phones on it. At this point, I'm not sure he even has a soft spot left.
