When do you actually feel the bond with your baby?

I know I'm supposed to feel this overwhelming love but honestly right now my 3 week old son just looks like a tiny angry potato that requires constant attention. My wife keeps talking about how much she loves him and I'm here thinking about how much I miss sleep and uninterrupted showers. Am I a terrible father? Everyone says it clicks eventually but when? I'm trying to be present and do the night feeds but part of me is just counting down until bedtime.
