I know exactly what you are going through. I have only been open since January, but I had clients here until 6:30 sometimes 7pm and it really took a toll on me and my children. I eventually had to tell my clients that I could no longer do the extended hours in the evening and that I would be closed at 5:30pm at the latest. One client rearranged their work schedule to be here on time, the other decided to look for care elsewhere. I am soo happy I did that though because my stress level is down and I actually get to spend some one on one time with my kids in the evening.
