SO works 3rd kinda annoyed. Rant

We have 3 kids ages 6, 2, and 1. His schedule is 11pm-7am work, sleep 8am-2:30pm coach high school basketball 3pm-6pm come home eat then take a nap from 6:30pm-10pm. Here's where I'm annoyed, why does he need to take a nap from 6:30-10? There is no time in his day for our kids. If he wanted to nap from 8-10 cool cuz I'm getting the kids to bed by 8. He gets mad when I say something about it. I'm a SAHM (not by choice) and I rarely sit down cuz I'm always cleaning cooking playing with the kids or running errands. I don't get naps. I get at the most 6hrs of sleep a night. I feel like if he can sacrifice his sleep to coach basketball then he should sacrifice his sleep for our kids. I always pictured my kids to have a super involved Dad, so I guess I'm just disappointed.
