Should dad help me in the middle of the night ??

Ok so I’m starting to get extremely annoyed, I wanna know if I’m over reacting.. my boyfriend works, so do I, (I take my son to work with me) so I literally never get a break. My boyfriend wakes up depending on what time he works around 5;00am or sometimes 6:30am... I wake up at like 7:45... is it fair that I ALWAYS wake up in the middle of the night to change and feed our son? Some nights are worse then others but he can wake up around 2-3 times a night... I ALWAYS get up and watching him just sleep peacefully is starting to piss me off. He says it’s cause he has to get up earlier but I’m just getting frustrated now... the only time he feeds and changes him it’s if the baby wakes up at the same time that he already gets up for work... so my question is, should I keep getting up all the time??? I get he works early but im starting to feel like this isn’t fair and im getting angry!!! (I don’t Breast feed btw) our son is 7 months old.
