mobile: what is dad's job in the middle of the night if working?

I was wondering if I can get some dad's opinion on this.

 My husband and I are expecting our first in about 5 weeks. He initially plans to take about a week off of work and then he will take another week off of work once when the baby is about 6 or 7 weeks old and I will be exhausted by then and want the help since the hype of the baby will have died down. 

 When my husband is off of work I know in the middle of the night I'll be doing the feeding (as I am breastfeeding) and then he can change the diapers. 

 What I want to know is what do most dads do for middle of the night when they have to work? Are most wives letting you sleep so you can work or do you still have some duties.
