I totally understand the "seasons" of life. As the kids grow, your schedule will change. It can be frustrating, but I like what you said: It's not good or bad.
ooh girl. 7th grade?! That's so rough. I took a year to try middle school after having been a high school teacher for the first 3 years of my career. The difference in maturity and personalities and habits was FLABBERGASTING. I wish you much luck and patience. Even 9th grade vs 11th grade is so huge for maturity and development.
