How is this equal?

I’m gonna try and keep this short. I have a 4 month old and a 3 year old.

My husband works and I’m a SAHM.

My husband takes the first nightly feed. Between 12-2am. He wants to and it’s so I can get some sleep.

My toddler is having a hard time right now and we can’t get them to fall asleep till 11-12. Pediatrician says kids just do it sometimes and it’s a phase.

Okay, so I can’t get to sleep until toddler is asleep, then me at 1am, husband takes 12-2am feed, I do the rest of the night. Last night baby fed at 2:30am, I got them at 6:30 and 10:00. He’s slow eater so I didn’t get back to sleep until after 7:30 because I also pump during the night and was up for the day just before baby ate at 10:30. So I slept a total of 7 hours but it was all broken/interrupted sleep. My husband went to bed at 3:30 because he stayed up. He slept until 1:30 this afternoon. He does this on his days off. So he slept 10 hours of uninterrupted sleep. I’m to the point that I would kill for a complete night of interrupted sleep.

He says that 7 hours total is still sleeping. I argue that interrupted sleep is not restful at all. As I’m always on alert for the baby waking up. He sleeps in the other room so he doesn’t have to listen for anything. Whereas for me once the toddler is up, I’m up for the day.

How is this fair? When I “sleep in” it’s with the baby in the room with me and not in a completely quiet room like my husband. He doesn’t see my point and I don’t know how else to explain it to him.
