Night time routine

Ladies how much did your husband's/boyfriends help you at night time with your infant? My wife and I have been butting heads for the past while with our 6 month old girl, and I'm starting to become annoyed with her. I'm all for helping her out at night time and giving her breaks but when I'm the one up literally half to 75% of the night walking around pacing and rocking back n forth 4-5 nights a week and have to wake up early (while she usually sleeps in an extra 2 n a half hours) to go to a busy physically demanding job is it not fair that she be the one up like 70% of the night so I'm not dragging my ass at work?
