Many of the answers here are talking about him not being interested in helping you with the baby. If that is the case then it is doubtful that you can get his help in the middle of the night. However, there are times when that isn't the case.
My husband was delighted when our baby boy was born. He loved Marcus (and still does three and a half years later). However, he slept through the baby. In the early weeks I was desperate for help and exhausted. I remember yelling at him one night because he wouldn't help. As I got louder and angrier he woke up surprised because he didn't realize that there was anything wrong. We have now had two babies and he still doesn't wake up to either of the children. However, we have gotten to the point where he helps me when needed (sometimes he does it in his sleep).
You can't wake him up in a way that is rude or violent because it won't get you what you need. Instead it will make things worse and it could cause other relationship issues.
The first thing that you need to do is talk. You want to try and do it when you aren't too exhausted (if that time exists). You should try to stay calm and not get angry. Tell him how you feel, what you need from him to get help with the baby, and then discuss with him solutions to the problem.
We currently have a seven month old. She is now getting to the point where most nights she sleeps through the night. On those nights that she doesn't I get up and get her, get the bottle, and change her (usually while Peter starts feeding her). He finishes feeding her while I go back to bed and then he takes her and puts her back down. It still has both of us getting up, but I don't feel as exhausted or as responsible because he is helping too.
While it certainly isn't easy and it can be frustrating, you can find a solution as long as both of you are willing to work together.
