It is not unrealistic to go to bed at 9pm. I run a busy daycare, open 7 days per week, have tons of laundry to do for both the daycare and a family of 6. I have chickens I care for, cats, dogs, and I read. I keep a very clean home, and I've learned to do all of that and still be ready for bed when the kids are ready.
It's all about learning to keep the kids busy while you clean during the day, never enter a room without doing a minute or two of picking up, never go to the bathroom without a minute or two of picking up, 1-2 loads of laundry per day, put a load in first thing, move it through during nap time, and if you can do it again just after supper. If not, laundry gets caught up on the weekend. Toys get put in boxes and only a box or two come out at a time. No meal is ever served without first picking up the toys. Discipline yourself and everyone in the house to finish what they are working on and pick up before starting a new project. Never start a meal in a messy kitchen. If you spend all morning cleaning the kitchen and don't have the ambition to turn around and cook, buy from a fast food dollar menu. You CAN sleep when the child sleeps and husband will have to be serviced a little less :) If he wants more time for certain pleasures, he can pay for a babysitter and take you to a hotel.
