I work two evenings a week and will start some homeschool preschool this fall just to see how it will work.
I would suggest reading "The Unschooling Hadbook". Even if you aren't planning to unschool it can help lighten your laod and give you confidence that your children will be learning evn when your aren't ina position to teach them. We spend about 1 1/2 2 or 3 times a week and dd is a year and a half above where she ought to be accidemically (and no offense to her but she isn't particularly bright compared to other kids. She is very normal if not a little slow to pick things up.)
Also i feel like homeschooling will help you maximize the time you do get to spend with your children. Imagine how little you would see them if you had to wait for your schedules to click.
Good luck to you as you embark on this journey. As you are learning and discovering keep an open mind about what it means to homeschool and let your creative juices flow.
The truest answer to violence is love. The truest answer to death is life. The only prevention for violence is for the heart to have no violence within it. We cannot prevent evil through any system devised by mankind. But we can grapple with evil and defeat it, but only with love—real love.
