The ladies are doing a great job of being truthful and of encouraging you that you can do it too!
We also run several programs at our house, so I know that you can do it! This year at our house, we'll be running LHFHG, Preparing, DITHR, and also have a 7th grader piloting much of our new ancients program (and our 2 year old little guy running around).
We'll have to start a new scheduling thread coming up here, so everyone can share their schedules for this year. I know it really helps to see how other moms do it!
