Sounds to me like he doesn't "get it" at all. As others have said, one wake up call in the night is very good for a baby of this age.
It is very difficult for you to feel sympathy for dh being woken up/slightly disturbed when you are doing the actual caring during the night. But maybe he should sleep in another room or on the sofa regularly (not necessarily always) as a planned thing rather than huffing off in the night.
Is there someone neutral who knows about these things and who he listens to who you can trust to give him a gentle reminder that this is normal for new babies? So that he doesn't just think it's you being a know it all? He does need to accept that you probably do know better than him at this stage bearing in mind it's you doing the actual feeding.
Some people are just really grumpy when woken up at night. However, it is his responsibility to rein it in and remember that you are doing the hard stuff and not him!
